@TechUST, Thanks for posting in Q&A. From your description, I know the scan physical check is working on not Intune managed device but not working on Intune managed device.
To clarify our issue, please check the following information:
1, For the working device and not working device, are they with the same OS version?
2, Review the Intune policies applied to the managed devices. Like security or device restriction policies might be interfering with the scanner service. Please check if there's any setting may related configure for the affected device.
3, Choose one test device with the same OS version, enrolled with a test user without any policy assigned and then test with the scan physical check to see if it can work.
Please check the above information and if there's any update, feel free to let us know.
