[PC] Futties De Jong causes Lost Connection after 5th PlayStyle+

Platform: PC
Game: EA SPORTS FC 26
Mode affected: Ultimate Team - Division Rivals & Champions

I found a reproducible bug with my Futties Frenkie de Jong card.

After adding the 5th PlayStyle+ to my Futties Frenkie de Jong (98) using the Futties 5th PlayStyle+ reward, I can no longer play Division Rivals or Champions with this player in my squad.

When I search for an opponent, matchmaking works normally. However, when the match is about to start and the stadium appears, I immediately get "Lost Connection".

Important details:
- Squad Battles works normally.
- Banger Only Tournament works normally, and I was able to complete the tournament and win the final.
- Rivals and Champions only fail when this specific De Jong card is in my squad.
- If I replace De Jong with another player, Rivals and Champions work normally.
- I tested a completely new squad without the evolved De Jong and could enter Rivals/Champions successfully.
- I restarted the game and PC.
- I also checked my network/router settings.
- Secure Boot is enabled and working now.
- The issue appears to be directly related to this specific evolved De Jong item.

I really don't want to remove/rollback the evolution because Frenkie de Jong is one of my favourite players and I specifically chose the 5th PlayStyle+ for this card.

Please investigate whether the PlayStyle+ evolution has corrupted or incorrectly configured this player item.

I can provide screenshots showing:
1. De Jong's PlayStyles
2. The 5th PlayStyle+ applied
3. The Lost Connection when entering Rivals/Champions
4. Rivals/Champions working immediately after removing De Jong from the squad
