FileNotFound exceptions when debugging unit tests

When debugging MSTest unit tests in Rider, two exceptions are thrown while the test runner appears to be setting up. These exceptions are not thrown when debugging the app, nor are any exceptions thrown in Visual Studio 2022 when debugging the same tests.

The two exceptions:

Microsoft.VisualStudio.TestTools.CppUnitTestFramework.CppUnitTestExtension

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.TestTools.CppUnitTestFramework.CppUnitTestExtension, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

These exceptions are not coming from my code, so why is Rider showing them in the first place? I don't use any C++ in this project. It's rather annoying having to resume execution from these two exceptions. And once I'm past them, test execution completes successfully with no errors.

Using Rider 2023.2.2, issue persists in 2023.3 EAP2
