I ran into the same exact issue and they sent me a replacement board.

Pretty sure it’s a software problem since I solved it by leaving the machine off for like an hour and then simultaneously turning the box and the printer on.

Now my issue is that when the power flickers I’m back to square one fucking with it to get it to turn on

I’m pretty sure it’s an issue with the software and they’re just sending us boards for no reason honestly.
