animation_john2.blend

System Information
Operating system: Windows 10
Graphics card: Nvidia 2070 Super

Blender Version
Worked: -

Short description of error
Blender crashes when object is rotated to a steep vertical angle and animation player is run.

Exact steps for others to reproduce the error
For animation_john2.blend

Play Animation
Select a bone (could be any other operator as well I think)
Undo (this will also jump back to frame 0 -- where we started -- which is the important part, starting animation at frame 2 or higher does not result in the crash)
Redo

Repeat until crash. Occurs between 2-5 repeats.

Also occurs at other similar high angles.

Cannot reproduce here.

Maybe I am doing the reproduction steps wrong?
A screencast of the steps in action possibly helps understanding the issue.
Could also help to try this with Factory Defaults (File > Defaults > Load Factory Settings)
Additionally it would be good to check if this error also occurs for you in a fresh build from https://builder.blender.org/download/daily/

Hi, I can reproduce the crash on master.

Will clarify reproducing steps.

Hi @lichtwerk , are you able to reproduce crash with these steps?

Play Animation
Select Bone.001
Undo
Redo
(Repeat last two steps until crash)

Yes, can repro now too.
(2.93 crashes for me as well though -- is this working fine for you in 2.93?)
Seems to only be the case if we are starting the animation from frame 1 (or below), if I start the animation at frame 2, the undo does not return to these critical frames and I can do these steps without crashing.
(Tbh, I dont even know why the undo jumps back in frames?)

This is a known issue with depsgraph and the rigidbody simulation system.
Undoing in certain cases will trigger a crash.

To solve this, we will new to rewrite the rigidbody code (and look into how to avoid this in depsgraph).

Thanks for the report. Marking this as known issue since it depends on the rigid body system which at the moment has no active developer. I'm tagging Sergej here anyways in case he wants to tackle any of those. Anyone wlse interested on that can also join the geometry nodes meetings to get onboarded.
