Fc26 Ps5-ps4 version

Fc 26 Game version on ps5 wont even update theres  seriously something wrong with it keeps crashing freezing and wont save setting or team setting sometime the sound of  commentary goes on and off. it's unplayable my players are moveing by there self defenders falling all over the place becoming hard to control like A.i taking control of everything i do opening up gaps passing ball back to the other teams soon as u score the other team runs straight up and scores becoming hard to control goal keeper scoring on goal running up the field. Iv uninstalled the game 5 time now checked internet settings and  it keeps happening payed 49.99 for this crap it need sorting now iv download the ps4 version and its happening again but not as bad also getting this message saying mismatch server validation does anyone else have these issues
