Thank you for your input. This problem is a big issue with this computer model and the impossibility of manually turning off the tablet mode in Windows 11.
I have a Chuwi Freebook with the very same problem. It goes crazy trying to detect when to go to tablet mode and when to come back from it, which makes it impossible to work with it.
I have just taken these steps you mention and the problem seems to be gone. I’ll post another message otherwise.
Thank you again.
