This is a native code crash suddenly ending the process. As it coincides with the game switching scenes that pretty conclusively tells it is an internal engine problem. Godot engine is sadly prone to crash when switching game scenes. So that’s likely what you got. I think some computers are more likely to crash than others.
The next release swaps to Godot 4 which has a ton of changes and upgrades. Could you try if the 0.6.6 RC works better for you: 0.6.6 Release Candidate ?
