Yes. 

I review the "xtal si not ready" messages again. It looks like it fails to
power-on before downloading firmware, so firmware might not the cause
you are encountering. 

Please try to remove module and reinstall module after booting to see how
it will be. Open a terminal, manually do below commands (try more than
one times), and share kernel log to us

  rmmod rtw89_8852be
  modprobe rtw89_8852be
