We are currently investigating undo related problems in T84397, your problem might be related. Please try to find step by step instructions that allow would us to reliably reproduce the crash and if this only happens in a particular project, try to create a minimal version of it where everything is removed except what causes the crash.

Could you please check if these problems persist in the current daily builds of 2.92 or 2.93?

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.

Thanks again for the report. If the problem persists please open a new report with the required information.

hey not sure if i should make my own or post here but seems to still be an issue in 2.9 so i wanted to give you guys some crash/debug files in hopes that it might help in this case its 100% reproducible every time regardless of how long ive been in blender even fresh start, but this time i create an object using bpy.ops.mesh.primitive_uv_sphere_add (4 or 5) called from speed sculpt (though i doubt its the plugin as this used to happen before i just found a reproducible method) ad a couple in the wrong place because their hotkeyed hit ctrl-z and can happen any time after 2 in a row.

hope this help guys and thanks for all the great hard work. if you need any more tests run shoot me msg.
