@ka_96, Thanks for posting in Q&A. From your description, it seems the authentication keeps looping when do Microsoft Entra joined.
Please try the following suggestions to see if it works.
- Please check if "Users may join devices to Microsoft Entra" included the enrolled user or set to ALL.
- Go to automatic enrollment setting, for WIP user scope, select None.
However, if the issue still persists, please collect the following information to continue.
- How many users are affected? Did if affect with all the devices when enroll with these affected users?
- What is the difference between the working devices and non-working devices?
- Is the affected device appearing in Microsoft Entra admin center after we sign in the user account?
Please try the above suggestion and if there's any update, feel free to let us know.
