[Bug] Show stopper: Copilot extension renders Rider unusable

[manavortex]

Describe the bug
Whenever I use the copilot extension, Rider completely freezes, often for several minutes at that time. The internet suggested various fixes, but none of them have done anything for me - I can either disable the extension completely and work, or live with the fact that Rider is unusable for minutes at a time.

To Reproduce
Steps to reproduce the behavior:

1. Open Rider
2. Click on "Github Copilot" or "Github Copilot Chat" in the sidebar
3. Wait until Rider recovers (it will eventually)

Log files
I've zipped my entire log folder to my OneDrive, since github didn't seem to want to host it. The threadDumps-freeze-xxxx subfolders should have the relevant intel.

Desktop (please complete the following information):

• OS: Windows 11
• Rider 2024.3.2
• Copilot 1.5.29.7524

Additional context
I have tried various versions of Rider and of the extension, and I reliably run into the issue with Rider 2024.3.2 and Copilot 1.5.29.7524. The internet suggests workaround for older versions of Rider, but I'd rather not downgrade. However, as it is, the IDE is effectively unusable as long as the plugin is installed.

How is this an idea? The plugin is literally unusable right now

@manavortex The label added is jetbrains-ides, not jetbrains-idea 😄

Thanks for bringing this up and proactively sharing the logs with us. We will file a bug to investigate why Extensions and Rider don't work well together.

@belaltaher8 Ahh, reading is hard :D Thanks!

Please do. This is a bad one for me.

Copilot plugin should behave the same on all compatible JetBrains IDEs. @jiec-msft please take a look.

@manavortex Thanks for reporting the issue. Unfortunately, I cannot reproduce the issue in my local env (Win11 + Rider 2024.3.2 + Copilot 1.5.29.7524).

1. While I'm analyzing the logs and thread dumps, could you please try to upgrade to 1.5.30-xxx version of Copilot plugin and see if the issue is still here?
2. And, could you also share a list of versions from "JetBrains Rider | Help | About | Copy and Close" menu, it will also include other plugins installed together.

In case you meet this issue to "Restart IDE" after update the plugin, you can work around with following steps. (We also include a fix in latest release but will take effect after it's installed.)

1. First disable the plugin & restart IDE
2. Uninstall copilot plugin & restart IDE
3. Install the latest version of GitHub Copilot plugin.

Hey @jiec-msft,
good news is that I can't reproduce the issue with the version that you linked. Bad news is, I've since deleted every single shred of data Rider had ever cached, along with any prior conversation with copilot. Given how quickly the panel loaded, I'm beginning to suspect that these things may be related.

However, my issue is gone (for the time being) and I'm rejoicing.

If you'd like to investigate more, you could try having a lengthy conversation with the AI (a few hundred posts) and then restart Rider.

@manavortex Great to hear this. Thanks for sharing the clue, and feel free to report the issue if it happens again.
