Musescore 4 is a bust for Windows 10

I have been using Musescore for years, most recently 3.6 for quite a while. I love it. After the regular prompting when I start Musescore 3 for a long while, I finally upgraded to Musescore 4 on my Dell Windows 10 laptop. It’s been a nightmare. Many display issues (ex. Mixer hiding behind score) and worst of all I can’t get rid of a ringing sound on the notes when I input them. And playback is very glitchy. I am uninstalling version 4 and going back to version 3.6. I hope you continue to support version 3.6 I am a pretty experienced computer user, so I suspect I am not alone about not wanting version 4.
