I am also having the same issue, tried a couple of fixes so far:

- Running on an Xbox Series X on the Internal memory
- Got around 7 freezes this morning in the first 2 hours just by teleporting around the city and going into cut scenes
- Transferred to SEA server Sephirot, freezes are way less common but they are still happening
- Also noticed the frame rate is worse than it was prior to the update, could be due to lag but feels worse than i've seen it
- Tried full restart and shutdown of Xbox before i realised it was happening to so many people

Side note - the annoying profanity filter is still in effect, cant type savage or raids for example but now i can type night so...something has changed
