Interesting - do you have a client version of this log? This simply contains warnings and no crash; it could be a recursive loop timing out, but I don't see any sort of recursive stack limit being reached.

Tried it with the full list of mods and got the same result, it only disconnects me on servers but the server itself never crashes

For now, you can disable the Villager Hats compat datapack by running this on the server:
/datapack disable "bountiful:compat-villager-hats"
I hope that helps!

Thanks! I'll try this

It also happens on single player worlds, causing "invalid player data" error
