InvalidOperationException is thrown when running tests repeatedly via "unity command run_tests"

Reproduction steps:
1. Open the attached “pipeline-set-result-repro.zip” project
2. Open the terminal and run the command unity command run_tests
3. Run the same command again
4. Observe the Console window

Actual result: InvalidOperationExceptions are thrown
Expected result: No errors are thrown

Reproducible with: 0.2.0-exp.2, 0.3.1-exp.1, 0.4.0-exp.1 (6000.0.0f1, 6000.0.81f1, 6000.3.21f1, 6000.5.7f1, 6000.6.0b7, 6000.7.0a4)

Reproducible on: Windows 11
Not reproducible on: No other environment tested

Notes:

• Unity CLI is required to reproduce the issue
• When a domain reload occurs, the symptom is mitigated and the exceptions no longer accumulate beyond two across repeated runs.

Errors:

• InvalidOperationException
