I do get incorrect context error with your script. Please provide complete operator or script that crashes Blender.

Im not able to pack bug example for you as Im using visual studio code blender plugin.

[URL ]] | In the video you can see example for inconsistency of the same code: ]([[ http://www.youtube.com/watch?v=JsNPAgQyJC4)

with visual studio bpy.ops.object.visual_transform_apply() does not work
2.ruining the script with blender from cmd works as expected
working_version.blend

working_version.py

I am affraid we can't help with this issue if running script "normally" does not cause the crash. It's more likely that this is problem with visual studio code blender plugin itself. Can you contact their developers?

The crash happens in rigidbody.py
line 121

I dont think its Visual studio plugin code but maybe a corner case.
I tried to avoid ops ,
if you know how I would start to write my own bpy.ops.object.visual_transform_apply() and bpy.ops.rigidbody.bake_to_keyframes()
using the python api it will be better workaround.

testing more as i`m writing this reply.
focus on context area type maybe.

Update:
crash also here:
ops.py

If script works when running it from commandline and not in IDE, I must suspect the IDE is doing something incorrect. In any case, to fix the issue a developer must be able to reproduce it, so that's why we need exact steps or sample files. If you can't provide these resources, we will have to close this report.
