How to remove failed installation

Hi. Recently I want to update my unity editor with a new version installation. I added the new version from ‘Add’ button, but the installation failed. Then I decided to download the new version from Unity download archive. Then I locate the installation directory from Unity Hub, and this what happened. I tried to Delete Files, but it says “Could not delete files”. Then I uninstall it via Control Panel\Program and feature. But still cannot get rid of it.

Sorry my english is bad.

I had this problem too. Unity Hub 2.4.1 just fixed the issue for me.
