Hello. Get a load of this one.
Windows 11 Pro workstation, and Windows 11 Pro laptop. Both at version 23H2 (OS Build 22631.4317).
Both using Chrome browser version 130.0.6723.59 (Official Build) (64-bit).
I have two student "test" accounts I have created for use with my chromebook deployment. I have been using them on my student chromebooks for years to check settings and see what things look like signed in as a "student".
On my Windows workstation, in the chrome browser, I can add one of these test student accounts as an additional profile so I can switch back on and forth to test settings.
On my Windows laptop, in the chrome browser, I can initially add (login) to the same student account as an additional profile. However, when I close the chrome browser and re-open it, I get this message:

And the profile that I just successfully added is DELETED!
I have never seen this action before, and for the life of me cannot figure out why it works on one device (my workstation) but not the other (my laptop), even though they are both the same version of Windows and Chrome browser.
