Unable to install Unity via Unity Hub. Could you help, I'm suffering for 5 days?

Question

Unity

Installing Unity via Unity Hub. Downloaded through the archive but needed an SDK file in the Hub. Everything is fine, but when everything is completed, nothing happens. Everything disappears in the folders that the unit has not been installed. Doesn't throw any errors etc. Stupidly the installation ends and everything disappears. Please help, I've checked everything but nothing.

Answer 1

I had that too. I don’t remember what, but 1 of these items helped me
1. Reinstalled Unity Hub
2. Added a folder with version
3 via Locate. Try to open the version in the folder and maybe it will be added there.
In general, I had a problem with the Unity Hub and when you often try to download versions, then additional problems occur (versions stop downloading at all). I uninstalled Unity hub, cleared system cache and reinstalled
