Unity 2020.1 Visual Studio not opening

I download new version of Unity which is 2020.1 and ı create a new project. But Visual studio not opening when i click scripts. Scripts are not opening even with notebook. There is just a loading icon a few seconds on mouse and thats it. No error or something. I look the external script editor, and it’s visual studio.
I tried to change other tool and visual studio back, and browse the visual studio file but it didn’t work.
I also tried to delete “.sln” and “.csproj” files, update visual studio editor and visual studio code editor, update visual studio to, but nothing is changed.
Before all of this i was using Unity 2019.2 and everthing was fine.
How can i fix this?

If you use SQL Server read this:

I had this problem, removed and installed multiple versions of Unity as well as packages and Visual studio tools for Unity, updated VS to latest version, nothing changed. Finally, I found that if Sql Server Management Studio (SSMS) is open, then Unity will send “request to open file” to SSMS, just close it and you’re fine.

Hope it helps

I fix it.
I just delete the “Visual Studio Editor” package and scripts are opening when i click it.

In my case I just had to update the Visual Studio package in the Package Manager

I still gets lots of issues when upgrading to a new version of unity with the visual studio editor.

I tried all the common workarounds

  1. Package Manager Visual Studio Editor etc updates
  2. Remove the project sln files on the unity project root
  3. Tried regenerating project files from the project settings

All not working

Only thing it leaves me with is a full install

  1. Remove Unity Versions
  2. Remove the Visual Studio from Add Remove Programs in Windows
  3. Install the version

Its much slower update but gets the job done!
