Same problem in 1.19.10. Unfortunately the game autosaved right when I was standing in the portal and about to go through, so everytime I load up my world I get the "generating world" screen for going from the nether to the overworld, and then it crashes. I'm stuck and I basically lost my 3.5 year survival world if this doesn't get fixed or if the fix doesn't work for worlds which have the bug.
