Help me please

I’m experiencing a career mode bug in EA Sports UFC6 on PlayStation 5. After I accidentally declined a fight offer, I accepted the next fight. Since then, my career mode has become stuck on “Sim to Training Camp Finished.” Every time I load that career save and accept the fight, it freezes at the same point and I can’t continue. Here’s what I’ve tried so far. I’ve restarted the game multiple times, restarted my PlayStation 5, cleared the PS5 system cache, and created a brand new career mode, which works normally. Since the new career works, it seems like only my original save is affected. This is my main career mode with over 25 fights completed, multiple title defenses, and a lot of progress.
