System Information
Operating system: macOS-11.5.2-x86_64-i386-64bit 64 Bits
Graphics card: Intel(R) UHD Graphics 630 Intel Inc. 4.1 INTEL-16.5.2

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-09-10 21:22, hash: eab26f1334
Worked: (newest version of Blender that worked as expected)

Short description of error
With a simple rigid body setup (see attached file), there are frequent crashes when doing simple adjustments such as moving the constraint around, rotating it, starting/stopping the animation, undoing some steps. There is not a single scenario leading to a crash, but performing a combination of these actions in succesion consistently leads to a crash (segmentation fault) within about 30-60s.

Exact steps for others to reproduce the error

I closed #91025 because I thought it was fixed, but it turns out the crashes still occur. I have found one reproducible way to get the crash:

With factory preferences, open attached blend file.
Press spacebar to start the animation
Press command-Z to undo and then shift + left arrow to restart at the first frame
Repeat the last step (command + z and then shift + left arrow) a few times
Blender will crash usually after repeating 2-3 times, sometimes a few more.

Hi, can reproduce now. Thanks for the steps :)

I am not sure if this is similar to: #78493 (Crash playing animation with rigid body) (Also, not able to reproduce #78493)

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.
