This just happened to me on my Realm. (Current Version 1.20.50) Went into my Nether Portal at -13171, 64, -946 in the Overworld, got stuck at "Building Terrain" had to force quit.
Have used the portal safely many times. Only thing I noted as different, was eating when I went through.
When I loaded back in I was at those coordinates, but in the nether.
EDIT: Another Realm member confirmed this happened to them earlier this week. Not sure if they were also eating, but it was a different Nether Portal with the same result. Teleport to Overworld Coordinates, but in Nether Dimension.
