Greetings @Jokrella

Welcome to the Unreal Forums! I see that you’re having some issues with an error. I’ve saw this exact error (Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000008) on another thread recently. The user had two different actors that had variables inside them with the same name. Once they addressed that, it resolved the problem. I would start there. Let me know if that fixes it!

Playing around I deleted all of these meshes and was able to launch session, but excuse me as I may seem clueless, but how could one have the same name? I’m glad I found the issue but I’m not sure where to go from here. Would appreciate any help. Also to add this is a pack from marketplace.

@Jokrella if you wouldn’t mind sending me a copy of your project in a zipped format that would be great to reproduce this issue.

@Jokrella the team is already aware of this issue and a fix is coming in a future release. Thank you for your patience!
