Minecraft worlds loading extremely slow

My world the same unplayable 

Windows 10 Bedrock v1.18.30.22 Beta is affected too. A Save and Quit on a world created in an older version takes 20 minutes. Everything mentioned in the following paragraph still apply to this version for old worlds. The Game is not playable on old worlds! If you create a new world in v1.18.30.22 Beta, the world plays normally including Save and Quit.

If you open a chest, it will not close which disables weapons, mobs, and most actions. I have not found a workaround.  I have deleted the game and reinstalled to no avail. I tried importing the last save, but it makes no difference. Basically, the game is not playable in the current Beta version.

Same issue, The mobs that are telported are not interactabl and get vanishes after you quit and join again.

Suppose you are at place 'A',then the mobs at this place will be visible but not interactable at base 'B'.

Base 'A' and 'B' can be millions of blocks away or just 500 blocks away.

I’m having same issue but when I log in it’s night no mobs around except 2 in water that don’t move. Village close by is just floating beds and can’t interact with anything. Some times I can’t even see anything or sometimes just a small amount of blocks And takes forever to log out. 

Preview 1.18.30.23 seems to have fixed my world…

I updated my Minecraft to Preview 1.18.30.23 and launched a copy of this world to see if anything had changed. The entities that got teleported to my new base are still there but I can interact with them now, I can load chunks normally again, the server time doesn’t spike anymore, the nether seems back to normal, et cetera. I managed to make it back to my old base through the nether, there was a bit of lag the closer I got to my old nether portal, it took a minute to load when I went through but my old base seems to be loading relatively normal now. The entities I suspected were teleported from my old base are still here so I suppose it actually duplicated them instead. My old base is lagging a bit more than it used to but it’s actually playable now. I’ve made a copy of my world in this new save in case the glitch happens again, but for now, it seems as I have my world back! If I find anything interesting while playing I’ll make sure to make another comment to update the current info on my world. So happy I can play on my world again!

EDIT:1

When I tried to save and quit it wouldn’t, I dashboarded and tried to load it again, it was doing the glitch again.

EDIT:2

I launched another copy of the world and everything seemed back to normal again, I saved and quit multiple times and it worked fine, it said “uploading world” instead of saving game though. I then tried traveling to my old base again and had the same experience (Kind of laggy closer I got). I saved and quit from my old base and now it says “Saving world” again and is taking a long time to save. It seems that the glitch has something to do with the chunks at my old base since it only starts glitching again once I travel to my old base.

EDIT:3

I let the world save and it took about 45 minutes. Once I relaunched it it seemed like it was struggling to load my old base but not nearly as bad as it was. I walked around my old base for a bit and then saved and quit, it went back to the “uploading world” screen and saved in normal time. I relaunched the world and it was doing the glitch again. I theorize that as long as I stay away from my old base the world should remain playable.

EDIT:4

I’ve let my old base load for an hour and a half while afk and it seems to be back to normal now. Or so I thought; As soon as I entered my old nether portal (overworld side) my game crashed. Every time I try to load that copy of the world my game crashes.

EDIT:5

I’ve been playing on a copy of my world for a couple hours today and it’s still loading normally. As far as I can tell my hypothesis was correct, as long as I stay away from the (what I believe to be corrupted) chunks of my old base (Overwold and Nether side), I can continue to play on this copy of my world normally. I’ll be making a copy of my world with each new update to check if a return to my old base will eventually be possible. For now though, I have to reacquire all the kinds of stuff I had stored at my old base lol.

EDIT:6

I went back to my old base today in the new update (1.18.30.27) and everything is loading normally again! I’ve traveled back a forth a couple of times, save and quit, restarted the game, et cetera, and everything seems back to normal! So based off of this I suppose the only current solution to this bug is to wait. Don’t play on your world for a while, let the beta continue to update, and it should eventually fix itself…

Here's a link to my world for Windows PC Bedrock World -197586509 1.18.30.22 20220309a:

I started this same Seed in the current version. Unlike the aforementioned world, the newly started world loads and plays correctly. I suspect old worlds are not converting correctly.

I have partially explored 3 maps. Now the newly created world will not load, see above screenshot. Minecraft is using 40% of the CPU and 30% of the memory. 

Please fix this. I almost lost my world completely if not for me copying the world before I loaded it up.

I can no longer reproduce this in 1.18.30.26 Beta. Is this still an issue for anyone else?

I can confirm that I am not facing this issue anymore. Thanks

I’ve still got the issue but it’s not as bad now.

Servertime spikes and FPS drops whenever I go to my old base but the games saves and stuff normally now.

Also a really weird thing with my armor, my Netherite Helmet is now invisible in my inventory and if I hit Y (Shift click) to take it off, it crashes the game instantly.

Yeah, so… the bug’s back.

I just had to delete a copy of my world because it said it was corrupted and the current version of my world crashes on launch. 

Haven’t encountered this bug again, seems fixed to me!
