Stability: GM emergency-restarts often on my machine, due to an "incomplete vertexbuffer state" exception

[gm-bug-reporter]

Description

Whenever I'm using the Code Editor 2, or making changes in a room, the GameMaker IDE suddnely closes without any warnings, and reopens automatically, without any error message or anything that I could use to debug where the problem could be. This is becoming tiresome, since it's happening a lot (sometimes even 2 times within a minute), thus making me going veeery cautious like where to put the mouse or where to scroll the code (sometimes it happens, sometimes not).

Steps To Reproduce

Open a code in Code Editor 2, and scroll it. Also, when it doesn't crash, sometimes it crashes when Feather tries to show suggestions about the code.

Code has a few #region, enums and #macro, along with functions, independently if it's editing code of an object or a script.

It happened also once when editing tiles in room editor.

IDE closed again, same symptom. I've found something in the ui.log when it happened. I also must inform that this "closing/reopening" didn't occour with the 2024 non-LTS version I was using a few days ago:
