UITestMethods fail in GitHub Actions CI

[mikebattista]

Describe the bug

UITestMethods fail in GitHub Actions CI (and possibly others). Commenting out UITestMethods allows the test pass to run and succeed. The same project with UITestMethods works fine when run locally in VS and from the CLI with the same commands used in the pipeline.

See additional context below for the exception. Working with the MSTest team on this as it may be a platform issue.

To Reproduce

https://github.com/mikebattista/TemplateStudio-MSTest-CI-RC

Fail with UITestMethod: https://github.com/mikebattista/TemplateStudio-MSTest-CI-RC/actions/runs/2735417690
Pass without UITestMethod: https://github.com/mikebattista/TemplateStudio-MSTest-CI-RC/actions/runs/2735455045

The pipeline is using the windows-latest Microsoft-hosted agent.
