For me the 1.18.33 update improved the freezing. Though there is a lag when breaking blocks and them disappearing, the blocks adjacent are pink and blue before the proper texture comes in.

I actually opened a gate got through it and closed it again before the gate moved!

There was a worse delay while the auto save was going on, it was at least playable with that until...It froze completely when it was raining, resulting in having to close and reload.

Hopefully you'll get to the bottom of this soon - I dare not go to the nether while the issues persist!

It is now playable at least - but still having issues during auto-save. Blocks take a long time to disappear after breaking. The sound is on time. Slight stutter after the save also as it catches up. Keep working on it! ¤

Edit: Game has crashed completely a couple of times now. not responsive to any key presses. having to go back to the home menu and close it. Then when I re-open it it has been shut down with an error message that there was an error with the program and it was closed... 

NOT FIXED!! ¤
