Test Explorer is finding tests, but not running them after upgrading to NUnit3TestAdapter v4.3.0

NUnit: v3.13.3 NUnit3TestAdapter: v4.3.0 Visual Studio Professional 2019: v16.11.20 Target Framework Version: v4.5

I’m running Visual Studio Professional 2019 and have many NUnit tests in my project. With v4.2.1 of the NUnit3TesetAdapter installed, the Test Explorer is able to find and run all my tests as expected.

However, a few days ago I updated my NUnit3TestAdapter nuget package from 4.2.1 to 4.3.0 and now my Test Explorer does not run any of the tests. It throws no errors and has no problem finding/displaying the tests, but whenever I try to run them, it says:

Test run finished: 0 Tests (0 Passed, 0 Failed, 0 Skipped) run in 172.1 ms

I can confirm that rolling back to 4.2.1, cleaning, and rebuilding the project fixes the problem so maybe the issue is a bug in the 4.3.0 package, however I wanted to check if there is any configuration I need to do in Visual Studio to fix this.

I have a similar issue with some interesting Test log output:

Test project *** does not reference any .NET NuGet adapter. Test discovery or execution might not work for this project. It’s recommended to reference NuGet test adapters in each test project in the solution. NUnit Adapter 4.3.0.0: Test discovery starting Exception System.UnauthorizedAccessException, Exception thrown discovering tests in ****.dll Access to the path ‘C:\Program Files\Microsoft Visual Studio\2022\Preview\Common7\IDE\InternalTrace.30660.log’ is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost) at System.IO.FileStream…ctor(String path, FileMode mode, FileAccess access, FileShare share) at NUnit.Engine.Internal.InternalTraceWriter…ctor(String logPath) at NUnit.Engine.Internal.InternalTrace.Initialize(String logName, InternalTraceLevel level) at NUnit.Engine.TestEngine.Initialize() at NUnit.Engine.TestEngine.GetRunner(TestPackage package) at NUnit.VisualStudio.TestAdapter.NUnit3TestDiscoverer.DiscoverTests(IEnumerable`1 sources, IDiscoveryContext discoveryContext, IMessageLogger messageLogger, ITestCaseDiscoverySink discoverySink) in D:\repos\NUnit\nunit3-vs-adapter\src\NUnitTestAdapter\NUnit3TestDiscoverer.cs:line 82 NUnit Adapter 4.3.0.0: Test discovery complete No test is available in ***.dll. Make sure that test discoverer & executors are registered and platform & framework version settings are appropriate and try again.

The test project is a multi-targeted C# project with net48, netcoreapp3.1 and net6.0. Executing the test for netcoreapp3.1 and net6.0 works fine.
