If you open a chest and move back in to a nether portal the second you right click it will appear to be open(even though it isn't) and wont reset until the player is gone. Unless you relog you won't be able to open anything containing GUI like anvils, chests, smithing tables, crafting tables, and grindstones. I would assume this is because the game thinks im still opening the chest, but it even works in other dimensions. This problem appears in versions 1.16.3, 1.16.2, 1.16.3, and 1.16.4. I couldn't get the affects versions to say that so i put it here.
