When checking the directory, /home/deck/ does not have any screenshot.

This isn't a really usable fix, but if this is found in the future: downloading from source and executing the python run.py code will solve this problem. I don't understand the discrepancy between source and flatpak, but something is broken there.

try to verify with flatseal if mpv shim can access and write into your home directory
