They at least acknowledged it now and disabled the dungeon, source:

Legion Timewalking Court of Stars Dungeon Temporarily Disabled

We’ve identified an issue causing some players to become trapped in the Legion Timewalking Court of Stars dungeon and we’ve temporarily removed the dungeon from the Timewalking dungeon finder. No one likes being stuck in Court. The Mythic+ version of the dungeon appears to be unaffected by this issue. We’ll let you know when we’ve got it fixed and opened again.
