Please help.

No idea why this would happen, kind of seems like a library mismatch of some kind. Make sure you have at least 2 GB of memory allocated to the game. Then maybe try re-downloading Litematica. If those don't help, then try disabling any other mods, although I tested it with everything else on the list shown except whatever those plasmovoice and su_plo_voice_common mods are.

If you are using the vanilla launcher, then maybe try deleting this file:

Problem was with this plasmovoice mod. Thanks for help.
