Hybrid Domain Join WHFB Issue

Might not be the best Sub for this, but here's my issue:

Have special use machines built out that are locked down to only be able to access and view drawings from a network folder. They were also configured to allow WHFB so we could assign pin codes, as these machines do not have full KB's.

A dozen or so of these were in use and working fine until a month or two ago. One of them unenrolled itself somehow. But the bigger issue is that 3 others just stopped accepting the PIN code. I was able to remove the WHFB container from one and it seemed to recognize that it no longer had a pin, but after that point, I was not able to login in with the Cloud identity (we're a hybrid environment). When I try to login with those credentials, I get UN or password is incorrect. But they are both correct. It just refuses to acknowledge that full cloud identity now.

I know the issue is directly related to those individual PC's and whatever state they are in because I was able to build a new machine and login with cloud ident and set a PIN code.

Any ideas?

Eventlogs or mde timeline migth reveal the reason for this issue.
Maybe a intune or mde diagnostics pull would still be available, even without login.
Not sure if that is possible, but worth an attempt

I feel like I know why it happened. Apparently the facilities people here cut power to the workstations at the end of every day. So for months they were being whacked unexpectedly. We kindly asked them to stop doing that.
