Most appropriate sub-area of Processing 4?

Core/Environment/Rendering

Processing version

4.4.1

Operating system

Ubuntu 24.04

Steps to reproduce this

"1. installing Processing in command-line with : snap install processing

2. running processing

3. trying to save a sketch

4. being unable to do so (the message is : could not read the contents of (hdd))"

Additional context

I can't open previous sketches either, as they are not displayed in the open window.
It is how I first noticed that my second hdd wasn't available as a saving location. But it turned out I was unable to save a sketch in my first drive home folder either. The first problem (second hdd not available) seems to be a "sandbox problem" (the command snap connect processing:removable-media answers snap "processing" has no plug named "removable-media"). For the second problem (home directory not available), I was advised to perform the installation with the command-line snap install processing --classic, witch seems to work.
Also, I noticed that the save as prompt-window is the default X window and not my kde theme window.

Would you like to work on the issue?

I can perform tests
