Strange Winlogon Behavior

I'm having a strange issue where within the span of one minute everything decides to logoff.

The general order goes like this each time:

Font Driver Host\UMFD-* logs off

SYSTEM logs on

Windows Manager logs off

SYSTEM logs on

SYSTEM logs off

Font Driver Host\UMFD-* logs on

Windows Manager logs on

Azure account logs off (I believe this is where I get kicked out)

SYSTEM logs on

I can provide the event logs, although they are extensive. Each time I'm logged off, the screen flickers back and forth before it logs me out entirely. Each time this general order is followed of logging on and off, but there are sometimes multiple of the same logon in immediate sequential order. This may be very vague, but if this sounds strange to anyone, I would be interested to find the cause of this. Should I suspect malicious activity? Other users on my network are starting to have the same issue. This happens the exact minute I get kicked out and returned to the login screen on Windows 10.

-Thank you

    Might also try from a clean boot using a local account for logon.
