Saves corrupt and games inventory vanishing

Inventory disappeared multiple times with saves not syncing and world spawn reset.

After playing and logging off. On restart I begin at world original spawn 0 x.0 location. My inventory is gone and I have to travel to my builds. All my savesbafter 1.19.62 update became corrupted and would not load. 

I got a backup to load after deleting cache, local saves and minecraft. It was older so the last months builds are gone. 

This is every time and if I copy, backup a world the file becomes corrupted. 

This all started with the uodate this week
