Thanks for the reply. The problem is that I have never logged into a VPN and also the name seems a bit suspicious to me, it's called "randomXYZVPN". Now that I have deactivated the connection with this VPN, I think there are still some active processes that, at startup, almost completely crash my PC due to a series of errors that appear. I honestly don't know how to identify and kill them.
As for the images uploaded in the previous post, I would like to upload an uncropped image, but unfortunately the only relevant thing that appears is that symbol on the bottom bar of the desktop, everything else closes and opens too quickly, it doesn't even have time to load the GUI
