Unable to login with diferent user when trusted_user set

Hello.

I set up my first HA for my parents, to help them control old heating system.
I set for them basic user (without admin privileges) and set, that this user is automatically log in, when accessing HA from local network 192.168.1.0/24.
I have the - type: homeassistant set.

Problem is, that I’m now not able to connect with my admin account. HA automatically log me in as basic user, and when I click on log out, it log in again automatically.

I see it as a bug. In my opinion manual log out should not do automatic login, or there should be option to change user to overcome this situation.

I don’t have any remote access to the system, so now I’m stuck without admin access (except directly by SSH to RPi).

Well, if you can SSH, can’t you just edit configuration.yaml?
What installation method is it?

I probably could, but it doesn’t solve the cause, but consequence.
I have it installed like supervisor on RPi OS Lite 64bit, because I use the RPi with touch display and relay contact at one piece:
