I get a black screen when attempting to enter the bios settings (or sometimes a hard lock in a couple of seconds if I get there) with ROG MAXIMUS Z690 HERO EVA BIOS 3603 (and onwards). I have unplugged all usb devices except the keyboard and used HDM...

The issue has persisted with the last 3 bios updates and have had to roll back.Have tried unplugging all USB  except keyboard. Used integrated graphics, HDMI.Any help appreciated. Can reproduce
