The last product key you entered can't be used on this copy of Windows. (0x8004E103)

I'm having a problem with my windows activation. The symptom first started when I open my Windows apps. A popup tells me that it's a file system error. I looked for answers on the Microsoft community and then I found out that my activation has errors. I don't know what happened but my laptop has been through a lot. The motherboard was changed since it got burned for leaving it open. Then recently around January, I changed my HDD to an SSD since it's getting slow. Everything was working fine throughout these events. Until now. I just updated when all of this happened. I can't even see my photos nor do anything much (download, update and use apps). I tried using the troubleshooter in the upper part of the photo but it gives me an error, saying something interrupted and shows the code I stated above. Is there a way through it? I promise, everything was well and it's about two months since I last freshly installed Windows on my new SSD. I tried chatting with the bot on Microsoft's website but it doesn't know this error code. Please help :<
