After upgrade to HassOs 3.12 it hangs at reboot

Hi, I upgraded HA to HassOs from v. 2.12 to v. 3.12 the last one.
Then when I try to reboot HA it hangs.
If I try to switch off it and switch on again it start fine.
What’s the matter?

I tried to restore a previous snapshot with HassOS v. 2.12 and it reboot fine.

Any suggestion?
