exePath_UserLevelNone failing when testing against source-build config #108476
Description
In our internal CI, the exePath_UserLevelNone test is failing on the main branch.
The stacktrace looks as follows:
System.Configuration.ConfigurationErrorsException: System.Configuration.ConfigurationErrorsException : An error occurred loading a configuration file: The parameter 'exePath' is invalid. (Parameter 'exePath')\n---- System.ArgumentException : The parameter 'exePath' is invalid. (Parameter 'exePath')

From looking through some CI logs: 5fd3f22 is good, and ef0c712 is bad.
The test failure happens on the main branch. The test is passing on the 9.0 branch.
