Gitlab-ci service on Windows cannot open my application


I am using gitlab-ci with Squish.

I am running my server, and whenever it comes to opening my application (startApplication), the UI doesn’t show up.

My service is running with the user I am using to open my session.

If I run my gitlab-runner using the console in my Windows runner, the application starts successfully and the test is executed without any issue.

I am seeing in google two thread that are about this issue, but I cannot access them:

Would anyone have a solution for that?
Is this an issue with permission on my service?
