[PC] [Bug] Sept 16 update: Tab crash, resets, disconnects, loading

Platform: PC (Steam) After the September 16 update, the game has serious problems, including the following: 

1. When entering the Firing Range solo, during loading I get sent back to the lobby and receive a message saying I have been disconnected from the server. (I am not sure whether other solo modes are affected.) 

2. My personal game settings are reset.

3. When the game first opens, it is extremely laggy and unresponsive. Every screen is very laggy, and it takes about 5 minutes for it to return to normal.

 4. Most items in the in-game store are stuck on an infinite loading spinner; only a few display correctly.

5. The notification panel in the bottom-right corner is stuck on an infinite loading spinner and cannot display normal information.

6. In multiplayer matches, pressing Tab to open the inventory causes the game to crash directly to desktop with no error message. While browsing Chinese communities, I saw people mention that opening enemy death boxes or Loba's Black Market can cause similar problems.

7. I have already verified the game files. I was still playing ranked the day before the update (September 15), and everything was normal before the update. I am confident this was caused by this update. There are many similar reports in the Chinese community, including negative Steam reviews from players who encountered similar issues.

Additional note: The September 16 update was released at 2:00 AM. As of now (September 24, 2:30 AM), 8 days have passed, and the game still has all of the above issues.

 I have seen related discussions on the EA forums, but there is no very clear and simple solution. The methods discussed in the Chinese community are too complicated, including creating a separate Windows account just to play Apex, changing the Apex save file location to avoid Chinese character issues, or modifying the registry. I am worried these methods could be detected by EAC and lead to a ban, so I cannot use them.

In summary, could EA or Respawn please let us know when these issues will be fixed, especially the crashes and loading problems? This is very important to me.

 I have played almost every season since Season 6. However, this bug has made the game completely unplayable for me, and this occurred even after I purchased the battle pass for the current season.
