Playing on Realm so don't know if it happens anywhere else. It happens randomly when you go through the portal it gets stuck on building terrain and I have to close the game and when I join back I spawn somewhere random. Happens when going in or out. I have had both. Once spawing in the Nether randomly thousands of blocks way from any other portal. In the over world spawned in a mountain and nearly suffocated if didn't have Netherrite with efficiency and good armour. Playing on Ps5
