I think I know how you feel. My laptop was bought sometime around 2019, but is not able to be updated from Windows 10 to 11. I have two options; buy myself a new one with Windows 11 installed or visit a local computer store to have my old one updated. The one I am currently using is an ASUS VivoBook Pro with Windows 10. It has a 4K (2160p) touchscreen, which I find very useful. Finding another 4K touchscreen laptop is really hard and expensive. But I am confident that I will find one someday.
Also, sorry to hear about your computer issues. Hopefully, they'll be resolved.
