This does not seem to fix the issue, still getting “LowLevelTestsRunner.Build.cs(19,65): Error CS0103 : The name 'Catch2' does not exist in the current context” error as usual.

If the issue persists, regenerating the project (Visual Studio, XCode etc) will ensure the third party files are properly included.
