Do I lose my projects if I uninstall an old Unity version?

I would like to download a new Unity version (2020.3.371), my version is 2020.3.32f1. After that, I want to uninstall the old Unity version. So my question is whether I will lose my projects from the old version if I uninstall them.

No, your project is separate from Unity software. it stays on your computer even if you uninstall all unity versions completely.
feel free to uninstall the old one.

@afshin_a_1 Thanks a lot!
