Unfortunately I haven’t yet solved this. According to the linked UE issue this is a known problem, so I’m hoping that Epic will be able to fix this (a fix is targetted for 5.5, but so far I haven’t seen a fix for this show up in the ue5-main branch). And yes, I’ve seen this happen not only in PIE but also in standalone and packaged games.
One thing I forgot to add is that the “workaround” mentioned in the issue description (i.e. setting the actor to never be dormant) doesn’t work for me. It does seem to solve the immediate issue, but I see a similar crash happen elsewhere.
