Unity scripts don't work: "Script class cannot be found"

Hello everybody,

A few days ago, a new error showed up on my computer: Unity scripts don't work at all. Every time I try to open (new or old) Unity projects, 2 blank errors appear (first screenshot), and when I try to attach a script to a GameObject, and alert dialog box shows (second screenshot). You can also see in the script import settings: "No MonoBehaviour scripts in the file or their names do not match the file name"...

I already tried to uninstall all Unity's related files, reinstall it, uninstall and reinstall Virtual Studio 2019 and SDKs, so if you have an idea of where it could come from, just tell me!

Thanks a lot,

Simon

Did you rename the script? - Samuel Goldenbaum
I didn't, the file name is the same as the class name. - Simon
Is the script C# or Unityscript? You've tagged both so it's unclear. - Llama
Sorry for this mistake, it's a C# script ! - Simon

The problem you're facing is called "Blank Error". Looking for Blank Error Unity you'll find many possible solutions.

For instance: https://forum.unity.com/threads/four-blank-errors-in-each-new-project.599980/

What fixed it for me was to "install windows update from this link to your 32 bit or 64 bit system accordingly": https://support.microsoft.com/en-us/help/2533623/microsoft-security-advisory-insecure-library-loading-could-allow-remot

Ok, so I installed MSVC v140 and v141, Unity 2018.4.13f1 and it seems to work now, after this I tried with Unity 2019.2.15f1, and I think there is an error with this version, I had the same problem.

But right now I can use Unity, that's what I wanted, thanks for all people who helped me !
