Failed to resolve profiler path from COR_PROFILER_PATH and COR_PROFILER environment variables

Question

I am trying to create and execute Shims from MS unit testcases in Visual Studio 2019. But, getting following error. How to resolve the following error. Thanks in advance.

Errror:

Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.UnitTestIsolationException
  HResult=0x80131500
  Message=Failed to resolve profiler path from COR_PROFILER_PATH and COR_PROFILER environment variables.
  Source=Microsoft.QualityTools.Testing.Fakes
  StackTrace:

   at Microsoft.QualityTools.Testing.Fakes.Shims.ShimRuntime.CreateContext()

Shim is not creating and unit test is throwing the error while creating the shim context.
