Oops, I submitted the same bug in a different place, I didn't notice there was one for reporting Realm-specific bugs. I'm gonna copypaste what I said elsewhere here, because it's the same issue:
"
Description
I'm playing on a friend's realm server. We had a previous nether portal set up, I wanted to make one a little closer to where we are living right now. I made a new portal and entered it to go to the nether, it dropped me off at the original nether portal created when I went into the nether the first time (expected). I wanted to go back through to see which nether portal in the overworld it was now connected to, the original or the new one.
Once I did this, however, the game was stuck indefinitely on the "building terrain" chunk of the loading screen. I exited after a while and re-entered the server, and it still hung on the same point of the loading screen. I booted the game up on my Switch and entered the realm from there on the same account, it still hung on the same point. I'm trapped until I can get a hold of my friend and see if anything can be done on the server end."
