Probably related to https://developer.blender.org/T98889

edit: Btw this bug needs more attention imo.

I can confirm the problem.
While in Release Build the crash occurs when switching instances, in Debug Build it occurs as soon as you enter sculpt mode.
And it has the same call stack reported in #98889 (Regression: Sculpting on a linked copy of an objects crashes Blender).

So it seems strongly related.
