Just starting today, I boot up my hotspot and a black screen comes on with little white writing saying “system data error” and doesn’t do anything else.

My question is this?
I have a backup file of everything that’s supposed to be on the micro SD cards, I can try wiping out an SD card and reloading the files, but do I also have to reload the pi-star image??

Also… does this or would this go beyond a micro SD card problem, because I swapped micro SD cards from my primary to my backup and the same thing happened. Turn it on… screen comes on black with white lettering “system data error”. Just started today, everything was fine yesterday today it’s “system data error” regardless of the sd cards the same result happens. So is this possibly a cpu chip problem on the pi computer itself where I’m going to have to replace the whole pi itself?
