Could not load `System.Runtime.CompilerServices.Unsafe.dll`

For some reason, it does work on my machine but doesn't on another, where it fails to load the System.Runtime.CompilerServices.Unsafe.dll, even so the file is present and the binding redirect is there.

One difference is, on my machine VS2022 was installed first and VS2019 after, and on the other only VS2019 is installed.

      <dependentAssembly>
        <assemblyIdentity name="System.Runtime.CompilerServices.Unsafe" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>

System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. ---> System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\System.Runtime.CompilerServices.Unsafe.dll' or one of its dependencies. The system cannot find the file specified.

This file is present, is has version 5.0.20.51904.

Strangely, fusion log shows another version is succesefully loaded (I don't know how to find out where did it come from).

Hello @TymurGubayev,

We apologize for the late response.
Is this issue still relevant?
Do you need our assistance?

@YuliiaKovalova funny thing, I don't quite remember what happened with this problem from over a year ago. Let's assume it's not relevant anymore.
