System posted in safe mode but it's working

I have had this hackintosh for 1+ year, it's a Z370 with an 8600K and I never had problems.

Yesterday I updated the bios to the latest release (2801; march 2021) and now when it boots up it says that the system has posted in safe mode.

If i enter the bios setup and exit, it works without problem.

Can it be the RTC write issues maybe implemented in the latest BIOS or do you think it's something different? Maybe I configured something differently after the bios update, but it works without a problem if I just enter the setup and exit without changes so I don't know.
