Unable to run UiPath Built-in command in local machine: Access denied

Hello all,

First of all, please bear with me as I am new to Ci/Cd concepts and am trying things now.
I would like to create a CiCd process in UiPath in which I tell the GitLab runner to go to the folder of UiPath studio and call the command “UiRobot.exe -file path/to/my/nupkg”. Now if I do this manually, I would be able to execute it. However, everytime i run the code in the pipeline, it always output error: “Access denied”. I already setup the runner to login as me when running, still it does not work.
I can confirm that the runner has the appropriate permission by testing if it could create an empty directory in the same folder where uirobot.exe reside and it did as expected.
Could anyone tell me, if this kind of operations possible to do?
Thank you very much for your kind help.

Kind regards
