Can't fly after upgraded to 3.7 firmware

After the upgrade, my drone paired with the controller but I can’t arm it. The propellers don’t move.
Reverted back to 3.6 and it works.
Any idea?

A tlog (of dataflashlog if enabled before arming) would provide the answer, if you need wild guessing, I think it was the gypsies.
