Cannot get out of lovelace custom header kiosk mode

I am currently using version 0.108.
I wanted to experiment with custom header kiosk mode but did it on the admin user.
Now i am stuck in kiosk mode and cannot access the normal front-end anymore.
I found 1 post about this problem where the solution proposed is to use the following adres in the browser :
Unfortunately this does not work and it stays in kiosk mode
Can somebody help ?
Thanks in advance

Could it be related to the latest 0.108 version ?

Thanks for your time !!
