Error when Compiling with Web Compiler 2022+: "The system cannot find the specified path"

Question

I have been on this problem for quite some time.

I am using Web Compiler 2022+ 1.14.11

And Visual Studio 17.8.5

For some reason suddenly the Web Compiler won't compile my scss file anymore.

Im getting the error in the Task Runner Explorer:

A:\Projekte\Privat\...\src\...\...> 
c:\users\simon müller\appdata\local\microsoft\visualstudio\17.0_899cbc51\extensions\bubxkjzz.tnk\WebCompiler.exe 
"A:/Projekte/Privat/.../src/.../.../compilerconfig.json" "wwwroot/css/app/test.scss"

Das System kann den angegebenen Pfad nicht finden.
Process terminated with code 1.

The error message is in German. I translated it to English: The system cannot find the specified path.

I have seen similar problems on the internet, and also tried many solution that all did not help.

I have tried:

• Reinstalling Web Compiler extension
• Clearing C:\Users\%username%\AppData\Local\Temp

I found a solution on GitHub to execute the prepare.cmd batch script in C:\Users\%username%\AppData\Local\Temp\WebCompiler1.14.11 but this folder does no contain any file.

I have also made sure that my Windows user has permission for all the folders (compilerconfig.json, localtemp, test.scss).

I have created a new scss file (test.scss) to test if it is a problem with the syntax or something. It only contains one stlye:

#test{
    background: green;
}

Anyone have a solution?

Thank you for your help.
