Game breaking log in bug

I don't know if it's just my machine but whenever I log into my solo survival world, my inventory goes to a reverted state ( possibly from when I logged out of the world first time in the snapshot)

For example I had a lot of enchanted books in a chest, which I applied to my gear, then I played for a few hours, build an iron farm and proceeded to log out.

When I  logged in after some amount of time, all the region progress (The blocks I placed and changes to chests etc.) was saved but my inventory reverted to the previous state with unenchanted gear and I lost all my enchanted books

I was playing on latest snapshot at the time (20w16a)

Also I had LAN opened (survival,no cheats) for AFKing purposes
