Aerobook plus slow boot after bios update

Hi, I have an aerobook plus i5 16gb of ram and a few days ago I received a bios update from chuwi support.
After flashing it, the PC takes about a minute to start windows.
I tried resetting the default settings, but it still doesn’t work.
The “chuwi” logo appears 40 seconds after switching on.
What can I try to do?
