This keeps happening to me whenever there is a foul with a cutscene. I just got disconnected after we won a penalty and the opponent got booked.
I've tried the affinity deselect cores 17-23 and it still happens.

Lasso didn't change anything for me, neither did every single step i've been given by EA Twitter crew, neither did a full optimization of my Windows.
I think I've lost almost half of my matches in rivals due to that bug. Unluckily I've finally managed to build the team of my dreams but I ain't able to use it due to this...
Since the bug has been reported since december, and Fifa22 coming in few month, I guess not.
I don't know if this fixed it for me but in my BIOS I disabled 'SMT' (Simultaneous multithreading, it's hyperthreading for Intel CPUs I believe) and I managed to play several games with fouls, cutscenes etc and didn't get the error once.
I haven't played clubs since that day to test it out again but that could be a potential fix.
No offense, but a fix does not including disabling half of your CPU threads. That's a workaround and a very bad one at that....
