Camera works with Gphoto2 but not with pibooth :(

[niccolov]

I'm trying to set up pibooth on a Raspberry 3 b+.

I managed to install everything and the environment seems to work fine.
I'm trying to use the system with a Nikon Coolpix S33 camera and a Canon Selphy CP910 printer.

Everything seems to work with gphoto2 and cups, but when I launch pibooth the camera stops working.

If I use the Nikon Coolpix S33 with gphoto2 I can take photos without problems.

Here are the results:

gphoto2 --capture-image-and-download --filename=test-2.jpg

Il nuovo file è alla posizione /store_00010001/DCIM/146NIKON/DSCN3059.JPG sulla fotocamera
File salvato come "test-2.jpg"
Eliminazione del file /store_00010001/DCIM/146NIKON/DSCN3059.JPG sulla fotocamera

However, if I launch the Pibooth program I always get the following error:

[ DEBUG ] pibooth : took 4.147 seconds
[ DEBUG ] pibooth : Activate state 'preview'
[ INFO ] pibooth : Show preview before next capture

If I use the command pibooth-diag I get the following message:

What could it depend on? How can I make pibooth work with the Nikon Coolpix S33?

Environment

• OS: Raspbian GNU/Linux 11 (bullseye)
• Camera: Nikon Coolpix S33
• Pibooth version: 2.0.8
• Gphoto version: 2.5.27

How Can I solve it to make it working?
