I think I lost EVERYTHING

This has happened at least twice. The first time I had to pull sync data from the cloud to be able to play again. It disabled auto sync so now my backup file loads into this white screen also. I can’t get past it. I can’t push buttons I can’t hear anything and I can’t join. If I lose everything I might honestly stop playing. I’ve lost 10days of playtime already the first time it happened but if I lose everything, I just might not do it again at all. Any ideas before I just delete this game? I’m playing on pS5. If it matters.
