FC 26 Ultimate Team stuck on loading screen on PS5, but Companion App works

Hi, I cannot access Ultimate Team on PS5. It stays stuck forever on the FUT loading/promo screen. I can access my club normally through the Companion App. 

I deleted my squads through the Companion App/Web App and created an empty/clean squad as requested. I then closed the Companion App, waited, and tried entering Ultimate Team again on console, but it still gets stuck forever on the loading/promo screen.

To give more detail: this started exactly after the new World Cup/International Tournament season update. Before that update, Ultimate Team worked normally. Since the new season started, I have not been able to enter FUT on console at all.

The Companion App works and I can access my club there. Also, when I disconnect my PS5 internet while the game is stuck loading, the FUT menu appears and shows my current coins and FC Points correctly. This suggests my club loads partially, but the console cannot complete the FUT synchronization.

I have already tried clearing cache, rebuilding database, deleting local saved data, reinstalling the game, hard reset, router restart, mobile hotspot, checking server status, deleting squads, creating an empty/clean squad, clearing pending items/rewards, and even downloading the PS4 version on my PS5. The PS4 version also gets stuck.
This seems to be an account/club-side FUT synchronization issue, not a normal connection issue. Could this please be escalated to the team to force logout/resync/repair my FUT club data
