My FC26 won't launch.

I think it's something top do with the anti-cheat, and I spoke with EA support about it. I turned off my anti-cheat (I use Norton), re-installed the FC26 anti-cheat, and verified the integrity of FC26 files multiple times (in steam settings). After all this, it continues to come up with a message saying that 'an unexpected error occurred when launching the game' with Crash reporter and it does a memory dump every time. Any suggestions?
