Windows 11 isnt compatible but im running as the os

I have no clue why my computer won't install the correct version of windows but I need help!!!!!! I have windows 11 pro on my computer and it's ran fine for 2 months before telling me that I have a digital license for windows 11 home, now my computer says when I try to clean install windows 11 home that it's not compatible. PLEASE HELP I'VE BEEN TRYING TO MAKE THIS WORK FOR 2 WEEKS, WATCHED EVERY VIDEO AND FOLLOWED EVERY TUTORIAL BUT THEN IT SAYS NOT COMPATIBLE?!?!?!?!
