pibooth: "Oops something wrong happens" when trying to take a photo on Fullscreen Pibooth

Hi everybody, i’m trying to use Pibooth to make a photobooth for a wedding on 16th of October but i’m having some issues right now. It’s very important to me to have something that work fine especially on this wedding day that’s why i’m requesting your help.

I can use Pibooth fine with a window size Pibooth but each time i try to use Pibooth in full size there is the “Oops something wrong happens” screen before the countdown to take the picture.

I’m using a Raspberry Pi 4 4gb with a raspberry pi camera V1 and a Canon EOS 700D with le latest version of Pibooth. For now the screen i’m using is my 4K TV as a testing setup with HDMI connection to the raspberry

Here is my config file :
