  • Hi vishnu prakash balotiya,

    If possible, you could share the main code about how you really run your coded UI test in your Nunit test. Please also share me the real VS version. I will try to repro this issue in my side.

    Anyway, you could share me your sample, I will test it in my side using the same Environment as yours.

    Best Regards,
