What works for me.

I changed the internet connection to another. In my case I use my 4G of my cell phone. After this the project will open. Then back to official connect. Just one time I do this…

This worked for me, I turned off my internet connection and it loaded instantly.

Turning off the internet worked for me also.

Just go to Library and delete this following files SourceAssetDB and SourceAssetDB-lock after that reinstall Unity hub

P.S. Forgot to mention you need to delete ArtifactDB and ArtifactDB-lock either

Had the same issue where Unity Hub wouldn’t open any project. Fixed by turning off Wi-Fi entirely

every time I try to open a project the loading icon comes up next to it and an application at the bottom of my Mac screen pops up for a split second, then the loading icon goes on for a another minute and nothing opens, idk what to do, anyone got ideas.

not sure if this will work for everyone but when i tried to launch an old version of unity the loading screen would pop up look like its gonna do something then disappear. So i navigated to the fold where my project is opened “assets” then opened “Scenes” then double clicked a scene and windows said what do you want to open this with and i selected unity and it worked.

Try removing the Lbrary folder from your project before loading it.

TY this saved my project!!!

Hey guys…

I’m trying to open my projects, but I’m having some problems.

Every time I click to open any project, Unity loading screen appears, but it open’s Unity Hub again and closes the project.

I tried Multiple versions, Reinstalling Unity, Opening project with scene and a lot of things, but nothing seems to work.

Video showing my problem:

If you have any ideias to help me, I would be grateful.

I’ve found if my unity won’t open, all I have to do is diconnect from my network, then it will start loading the project, after I see the splash screen, I just reconnect my wifi.

By remove, do you mean delete?

Same problem here: trying to open my project from hub and it’s get to ‘loading scripts’ and then nothing happens. I tried to remove Library folder and my project opened, but it was empty… If i restore folder - it wont open again.
Nothing above helped.
