Troubleshooting • Pi zero cluster error

I have a pi zero cluster that works just fine, however it recently started displaying this error:

Failed to load HAT overlay
dterror not a valid FDT - error 9

I have installed all updates. Does anyone have any ideas what's causing this & how to fix it?

Thank you!
