Buttons can't be placed on walls or fences anymore

My PC crashed and when I got back into Minecraft my world was gone. (No experimental features enabled)

When in creative, items that get picked up while having a full inventory disappear

Blocks disappear after being placed, previously broken blocks come back

Stairs and slabs lighting glitch under solid blocks

Maximum render distanced lowered for no reason

Skins not loading

Minecraft can't connect to anything online
