@RK-IT, Thanks for posting in Q&A. From your description, I know we have created a multi app kiosk profile and assign to different accounts. Based as I know, the profile is for shared devices, and we need to assign the profile to device group.
In the picture, I notice we have set "user logon type" and in Attempt 1, it seems we deploy a custom CSP with the same setting. If so, it will cause conflict as they actually using the same CSP to deploy. Please remove one.
After we remove any conflict configuration profile, if the error still exists, we can go to event viewer to check the event log under Applications and Services Logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostic-Provider > Admin to see if any error exists.
Hope the above information can help.
