I never had the slightest issue with Windows 11. I updated a month ago, I created a new favorites collection in the start menu, and was done. Everything is working fine as with Windows 10.
Don't laugh, but the main reason to update was the centered start button and centered task bar. Just a must for my ultra wide screen monitor.
It's very important of course to keep the video driver current. Afterwards, I updated the Nvidia driver to current as well as the Intel drivers for the Intel iGPU that has no monitor connected but is present nonetheless. I did a full reinstall (delete settings) for the Nvidia driver to get rid of any settings that might have been Windows 10 specific. I don't know any, but just in case.
