Veyon can't login to remote windows pc because last logged in user loads at startup

[dalagiorgos]

We manage a small computer lab with 14 Windows 11 PC.
Each PC has two users: admin and student
I try to remotely login as admin via Veyon
The user logon screen loads but the last logged user pops up (i.e. student) and Veyon "types" the admin password to the student account and obviously fails to log in.
How can I fix it?
