Windows 10: Windows 11 now not active and won't let me activate. How to fix? I DONT KNOW WHAT TO DO

A few days ago Windows 11 stopped being active and it won't allow me to activate it again. During this year, some parts of my computer have been changed, the hard drive and the battery. I attach screenshots of what appears to me. I used ShowKeyPlus to view Windows product information. PS: I honestly don't have any knowledge about computers, so the support that I was able to find online for the error that appears is of no use to me, because it doesn't tell me exactly what to do. Thank you.

Windows activation . . .

In the Windows activation status page is it still showing as activated, or do you have something like 3 days to do it in?
