The file has a corrupt selection history element index, can you provide steps to make another object that crashes as this file does?

I can’t repeat it on new project but if I create new project then append object Helper from test-bug.blend (File->Append...) then Blender also crashes. This is file (test-bug.blend) was created in Blender 2.90

Closing, can re-open if you manage to create a corrupt mesh from scratch.

Note that running bpy.context.object.data.validate() in the Python console will fix this for the current mesh.
