Python quit unexpectedly when terminating DAP UI

[Chamal1120]

I have an issue where macOS gives this error message "Python quit unexpectedly" on every time when I try to terminate, exit or reach the end of the program that I'm debugging. Apart from that the debugger works as expected.

OS - macOS Monterey 12.7.5 (intel macbook)
Package manager - homebrew (python also installed with brew)
neovim version - v0.10.0 (installed with brew)
Plugin manager - lazy.nvim
**Debugpy installed with mason tho. (actually I don't how it works. I just copy pasted some codes.)

below is my lua code related to debugging plugins located inside parent folder > lua > plugins

return {
  {
      "williamboman/mason.nvim",
      config = function()
          require("mason").setup()
      end,
  },
  {
      "jay-babu/mason-nvim-dap.nvim",
      config = function()
          require("mason-nvim-dap").setup({
              ensure_installed = { "python" },
              automatic_installation = false, 
              handlers = {
                  -- Custom handlers for specific adapters can be defined here
                  python = function(config)
                      config.adapters = {
                          type = "executable",
                          command = vim.fn.stdpath("data") .. "/mason/packages/debugpy/venv/bin/python",
                          args = { "-m", "debugpy.adapter" },
                      }
                      require('mason-nvim-dap').default_setup(config)
                  end,
              },
          })
      end,
  },
  {
      "mfussenegger/nvim-dap",
      dependencies = {
          "rcarriga/nvim-dap-ui",
          "nvim-neotest/nvim-nio",
          "mfussenegger/nvim-dap-python",
      },
      config = function()
          local dap = require("dap")
          local dapui = require("dapui")

          require("dapui").setup()
          require("dap-python").setup()

          dap.listeners.before.attach.dapui_config = function()
              dapui.open()
          end
          dap.listeners.before.launch.dapui_config = function()
              dapui.open()
          end
          dap.listeners.before.event_terminated.dapui_config = function()
              dapui.close()
          end
          dap.listeners.before.event_exited.dapui_config = function()
              dapui.close()
          end

          vim.keymap.set("n", "<Leader>dt", function() dap.toggle_breakpoint() end, {})
          vim.keymap.set("n", "<Leader>dc", function() dap.continue() end, {})
      end,
  },
}

p.s. - I'm a total beginner to neovim and lua and I might have made a lot of mistakes. I hope someone would help me out to correct my code.

If I use the python from homebrew, I get the same message in the same condition. If I use the python from anaconda, it will not show the message. My system is macOS 14.5(M1). I use a plugin called venv-selector to change environment.

@BLACKSWORD0 can you tell me more about your conda setup?

1. Can I use it alongside my macos default python + hombrew python?
2. did you installed conda from brew? (if so what is the exact brew command?)
3. How do I set the path for the debugpy in my lua plugin with conda?

1. Yes, we can use different python virtual environment, so we can use anaconda alongside homebrew python. But I don't use macOS default python.
2. Yes, I install cask anaconda from homebrew.( brew install --cask anaconda).
3. I use a plugin called venv-selector to change environment. You can view its doc for more details. My config about them is following (My full config of python bases on astronvim, so I just show this part.):

  {
    "linux-cultist/venv-selector.nvim",
    dependencies = {
      "nvim-telescope/telescope.nvim",
      "mfussenegger/nvim-dap-python",
      "nvim-lua/plenary.nvim",
    },
    opts = {
      anaconda_base_path = "/opt/homebrew/anaconda3",
      anaconda_envs_path = "/opt/homebrew/anaconda3/envs",
      stay_on_this_version = true,
      dap_enabled = true,
      settings = {
        options = {
          notify_user_on_venv_activation = true,
        },
      },
    },
    cmd = { "VenvSelect" },
  },

  {
    "mfussenegger/nvim-dap-python",
    dependencies = "mfussenegger/nvim-dap",
    ft = "python",
    config = function(_, opts)
      require("dap-python").setup("python", opts)
    end,
  },

But I don't use debugpy in mason, I just install debugpy in ~/.virtualenvs. "venv-selector" will find it automatically. If you want, you can change the config of "venv-selector" to find debugpy in mason.
The following is an example to show "venv-selector":

@BLACKSWORD0 Thanks will look into this and give you an update.

I have the exact same issue, i use python 3.12.4.

This is my setup for nvim dap.

return {
	{
		"mfussenegger/nvim-dap",
		-- stylua: ignore
		keys = {
      { "<leader>s", function() require("dap").continue() end, desc = "Debug: Continue" },
      { "<up>", function() require("dap").step_over() end, desc = "Debug: Step over" },
      { "<down>", function() require("dap").step_into() end, desc = "Debug: Step into" },
      { "<right>", function() require("dap").step_out() end, desc = "Debug: Step out" },
      { "<leader>b", function() require("dap").toggle_breakpoint() end, desc = "Debug: Toggle breakpoint" },
    },
	},
	{
		"rcarriga/nvim-dap-ui",
		dependencies = { "mfussenegger/nvim-dap", "nvim-neotest/nvim-nio" },
		config = function()
			local dap = require("dap")
			local dapui = require("dapui")
			dapui.setup()
			dap.listeners.after.event_initialized["dapui_config"] = function()
				dapui.open()
			end
			dap.listeners.before.event_terminated["dapui_config"] = function()
				dapui.close()
			end
			dap.listeners.before.event_exited["dapui_config"] = function()
				dapui.close()
			end
		end,
	},
	{
		"mfussenegger/nvim-dap-python",
		ft = "python",
		dependencies = { "mfussenegger/nvim-dap", "rcarriga/nvim-dap-ui" },
		config = function()
			local path = "~/.local/share/nvim/mason/packages/debugpy/venv/bin/python"
			require("dap-python").setup(path)
		end,
	},
}

A temporary solution would be to run this in the terminal:

defaults write com.apple.CrashReporter DialogType none

To enable it again:

defaults write com.apple.CrashReporter DialogType prompt

You must restart for the changes to take effect.
