Hi,
Thank you for posting in Microsoft Q&A forum.
Please make sure the Antivirus exclusions is deployed to the users.
We can also try to check Microsoft Defender Antivirus Exclusions manually on the device. Open Settings –> Update & Security –> Windows Security –> Virus & threat protection –> Virus & threat protection settings –> Click on Manage Settings –> Scroll down to find Exclusions –> Click on Add or remove exclusions. Can we see the exclusions you have configured in Intune here?
Thanks for your time. Have a nice day!
Best regards,
Simon
