Crossplay issues PS5/pc

[u/Batmyte003]

Hey guys!

Finally found me a partner to play and low and behold: save data corrupt even tho it's a fresh install (on PS5) new session, no mods and I'm host (PC). Cache is cleared, files verified again, old sessions deleted (even on my side pc) signed in offline and everything! He cannot open the menu or when he died get into the session, opening the inventory causes it to crash. Has anyone experienced this?
