Same problem...
I haven't used the tablet for a long time. Yesterday I turned it on and windows update indicated that there was an update available. So far, turning it on has been problem-free. The update was made to UEFI version 16.106.143, and from then on, the tablet stops for 1 minute before starting to load the operating system. Entering the BIOS also takes the same amount of time, and the BIOS is completely sticky.
The cause of the problem is clearly the new UEFI version.
MICROSOFT doesn't see it ???? Tested by MICROSOFT ???????
