Hello, there is high probability this come from your GPU, can you try to update the drivers please ? Also can you send me an address mail where I can send you a debug version, hopefully we could get error logs before crash.
Thank you for your reply. Since I'm on Linux, there really isn't any sane way to upgrade my GPU drivers any further. My system is fully upgraded and I'm using a fairly recent version of Mesa (20.3.4). I also regularly use quite a few other programs based on Godot (including Godot itself) and never really experienced this particular issue before. I will send you my E-Mail adress via PM.
