InTune Enrollment Loop for MacBook loops at i.manage.microsoft.com during setup

Good afternoon, is anyone using InTune seeing issues with enrollment?

I have ABM set up with InTune for automatic enrollment. The InTune instance is fairly new and simple. In the last two months, I have rolled out four machines with painless success. I bought a fifth machine and it gets stuck during the Remote Management portion of enrollment, in an endless loop of connecting to http://i.manage.microsoft.com/. Between the last enrollment and now, absolutely nothing was changed in InTune.

The machine is a M4 MacBook Air on OS version 15.7.1. I have reset it multiple times to no avail. It doesn't seem to be getting stuck on anything and shows up as responsive in InTune.

If I force the machine off and back on, it allows me to complete enrollment, but after a reboot, I get the initial setup screen and when proceeding past that I get a black screen that never progresses.

I assume this is an enrollment issue. Where would you suggest starting to troubleshoot this? Has anyone seen it so far? The last successful setup on my tenant before this was around three weeks ago. Thanks in advance!

Other things I have tried:

1. Renewing the ABM enrollment token
2. Removing troublesome configuration profiles
3. Creating and using another enrollment program token profile
4. Different networks, including the network I successfully enrolled previously successful machines in
5. Different user accounts with the correct license for InTune management
6. Logging into ABM to make sure that there are no pending terms to accept. I confirmed that I accepted the latest new ABM terms directly from ABM.
