So, If you are deploying as Admin (I’ll have to assume you mean SYSTEM?)
What is the Install command line you have configured in Intune for this deployment?
I’m wondering if maybe the application is showing a message that is not being shown to you as this will appear in the SYSTEM context (not the logged on users context).
By using ServiceUI.exe you could see if this resolves the issue
