Crash when opening 160 scenes in EditorToaster::_error_handler_impl when MessageQueue runs out of memory

[rakkarage]

Godot version

v4.0.2.stable.official [7a0977c]

System information

Windows 11, Core i5-12400F, RX 6600

Issue description

i have a project with 80 animations, 80 animation scenes, and 80 test scenes
converting to 4 sometimes need to open a scene and save it to trigger a conversion
after doing this and reloading the program crashes and disappears with no message after showing all windows loading in title bar

so i made a simple test project and duplicated a bunch of windows, open them all and same insta-crash

is there some way to close windows from outside of godot? because it stuck in this state where it cannot open because too many windows open but cannot close windows because cannot open?

thanks

Steps to reproduce

• make a simple scene and duplicate it 160 times (80 is ok)
• open all scenes
• if nor crashed yet close and reopen

Minimal reproduction project

https://github.com/rakkarage/TestWindows

[fire]

Notes on things to try for the development team:

1. animation issue?
2. editor issue?

is there some way to close windows from outside of godot? because it stuck in this state where it cannot open because too many windows open but cannot close windows because cannot open?

It's in the project's .godot folder, I believe the editor subfolder. Try renaming it before opening the project.

i got it debugging in vscode and visual studio to test and get more details

ERROR: Failed method: EditorToaster::_error_handler_impl. Message queue out of memory. Try increasing 'memory/limits/message_queue/max_size_kb' in project settings.
   at: MessageQueue::push_callablep (core\object\message_queue.cpp:120)

shows LOTS of this message in vscode when crashes

half these files have id collisions too i don't think that is related tho because my original used 160 unique scenes and same problem

i don't know what i am talking about but from call stack looks like it is doing infinite calls to EditorToaster::_error_handler when i get the exception

The maximum number of stack frames supported by Visual Studio has been exceeded.

This might have been fixed for 4.1 with #75940 which made the MessageQueue growable.

That being said we should still aim to prevent this infinite loop in EditorToaster and not use the toaster to display error messages that originate in itself (like this one about running out of memory). I think we might have one or more existing issues about this but don't have time to do a deep dive right now, so keeping this open.

thanks ya seems fixed for me in a 4.1 build
can open em all, close em all, open em all again, quit and reload them all no errors
sorry
