Menu bar missing and keyboard not working after forced shutdown

Hello everyone,

I work as technical support in an University where we have more than 200 classrooms equiped with Mac Mini. There is a mix of 2014, 2018 and M1 2020 models across the campus (all running macOS Monterey) and we are facing the same problems with all of them:

After a forced shutdown by long pressing power button, regardless of whether we select Cancel or Open in "You shut down your computer because of a problem" window, desktop and dock load correctly but not the menu bar. This is not the only unexpected behaviour: Close/Minimize/Maximize buttons respond erratically and Keyboard does not work if you try to write in a TexBox or an app such as Notes.

All those Mac Mini have the same configuration: Just one user with automatic login, Remote Administration activated, and the following program list: Faraonics DeepFreeze, Microsoft Office 2019, Microsoft Teams, Google Chrome, Mozilla Firefox, Logitech LogiTune, Zoom, Skype, and VLC player.

We have tried without success:

-Restarting in Safe Mode

-Uninstalling one program at a time, trying to detect if the problem was caused by a specific one.

-Deleting programs Cache

-Uncheking "Hide" related settings in Dock and Desktop configuration.

-Restoring default settings across System Preferences

-Reinstalling macOS Monterey from scratch

-Installing one program at a time after fresh Monterey installation, to find out if the problem appears after executing a specific app.

-Resetting NVRAM and SMC

-Deleting all Library/Cache data

We ran out of ideas. Any suggestion about what we could do? As I said before, the problem persist in 2014, 2018 and M1 2020 models.
