Unity editor keeps uninstalling itself

The Unity editor keeps uninstalling/deleting itself every time I launch my laptop.
I have tried to completely remove Unity (the Hub and the Editor) from my computer and re-download them, but the problem remains: it works fine after I re-download it, but as long as I shut down/restart the computer, the Editor uninstalls itself. So, I have to reinstall it over and over again…
Is there any way to solve this?

I don’t believe the editor uninstalls itself, I think it may just be hidden because you’ve set different path or something, in Unity Hub make sure the install path is the same, or you can click “Locate” to manually find where you installed it.
