Probably your CPU doesn't meet minimum standards. That was my situation, one rung down from qualifying. I had other extensive problems. One hard drive with a lot of data on it was beginning to fail. The SSD which had the OS was only 256 gig. Seven years ago, that seemed adequate, but it was full, so I would have to replace it and move the OS over. So, I just bought a new computer...
I bought a new NUC myself but have yet to do the changeover. I need to get it done though and will. My old NUC has served me well but I know this new one will be even better !
