I haven’t personally experienced crashes yet, but I’m aware that Regenerate has been exhibiting suspicious behavior.
Before regenerate rig, make sure to apply Clean Up > Purge Unused Data to ensure that any old Armature is completely removed. In my environment, this step usually helps avoid issues in most cases.

However, it seems that finding a fundamental solution might take some time.
