I’m having the same problem when I try to open my Level or my Sequencer from this Level. Looks like it happens when I cancel the render using Movie Render Queue. Any fixes yet?

Also, have this issue. Trying to interact with the level file at all causes the error. EX: Right clicking it, trying to delete it, opening it; unreal crashes.

I switched from DX12 to Vulkan in project settings and I now have a lot fewer crashes. Never had this problem with UE5 EA.
