Tried to connect via Teamviewer and the system isn't allowing that. So something is different from how it shipped to you.
You can try rebooting it gracefully. Do NOT power cycle it (ever - if possible).
My guess is it was in the middle of an OS update and got power cycled which shortcut the scripted process so now it's not happy.
Put a monitor keyboard / mouse on it and see what it is doing. Click on TeamViewer icon on bottom right tray to see if that is running. If the TeamViewer license is needing attention, grant approval.
Try doing an update via the updater icon on bottom right next to Teamviewer (it will display if there are updates). allonis is the password that might prompt up.
To delete a driver / app, bring that up in the Drivers / Applications window and click the X on the bottom right and restart myServer.
If you need more help let us know.
Worse case you might need to reimage the NVME drive (internal).
