I created a world and turned it into a realm. While working on the world (I was doing a lot of stuff on command blocks to export to the realm), I placed some command blocks in the end dimension. These command blocks were tp commands, tag commands, and particle commands. Then, after going into survival mode to jump into the void and return to the overworld, I found that I couldn't use any commands, I couldn't go into my inventory, mob ai froze, etc. I saved and quit, but it couldn't save for like 20 minutes straight, so I closed the minecraft tab. upon rejoining, I thought everything was working fine, but after like 5 minutes, the game froze over again. This happened in the realm too. The realm didn't work for playstation or for my windows device.

The command blocks were working completely fine and I never had the game freeze until now. I have no clue what might be causing this, since it could be me closing the app prematurely, the more recently placed command blocks, or the update I just did on my windows device (though the last option seems unlikely)
