I'm really sorry for not being able to attach these as individual files, I don't know why it won't upload them it just gets stuck on uploading. Listed below are Client, Launch Error Dialogue, crash report prior to world being unable to open (seems permanent, tried disabling mowzie's, rollback, etc), and modlist.

I would appreciate any help, my wife made this modpack and we've been playing on it a lot and really really want back in. Thank you.

Client: MultiMC version: 0.6.12-1530
LWJGL 3.2.2, Minecraft 1.16.5, Forge 36.1.0
