Unity Editor won't load.

This has been happening to me for a few months now. Basically, whenever I select/create a project in the Unity Menu, it will load for a bit and nothing will happen. In Task Manager, however, it says it is running. I try waiting, reinstalling Unity, restarting computer, practically everything people say in other posts. But nothing works. I’m currently using Unity 2017.1.0f3 on a Windows 10 computer. I hope someone can help me soon.
Thanks,

This is happening to be too. i just want to code and i cant. I’ve only gotten it to work 1% of the time, and when i do i just dont shut it down/ shut down my computer

Are you giving it a minute or two to load? Also, there may be some clue in Editor.log Unity - Manual: Log files

I am now experiencing the same problem. I’ve tried pretty much every solution on numerous threads and still no success. I was working in Unity just fine and then this afternoon I get the blank grey screen. I haven’t changed any settings or anything. I checked an editor file that i found in the following directory location C:\Users"name"\AppData\Local\Unity\Editor and it had the following. Any ideas what I need to do to fix this?

Check the install of your project packages, e.g. reinstall URP, verify if it can import updates, if not, delete specific package folders and renew they. If no Logs (simple, doesn’t load), try review your licenses.
