STM32U575ZIT6 USB FS problem

Hello all, i got a firmware configuration problem,

 

basically im using USB in FS modem and when i plug in the usb to  the pc what happens is that sometimes it can be recognized and i see a network disk called ''boot'' but most of times it cant be recognized, so i gotta power up again the whole circuit until it can be seen, i thought it would be a frequency problem, but i already saw that configuration is set to 48MHz , so its correct, i added also a delay before initialization of the usb but it still doesnt work, what else i can try? can someone give me some tips? i already read on many forums but still didnt find out

Hi @USER291279641 
Would you attach screenshot of USB Device manager?
