Bug

Describe the bug

When opening a folder in Biscuit, I get these errors in the logs (standard output/error):

>  ~/Downloads/biscuit .
The environment does not allow connecting to the splash screen. Are the splash resources attached to the bootloader or did an error occur?

Biscuit still works, but if I try to open an image, it simply opens a text editor with no contents (not sure if related).

System Information

• OS: ArchLinux
• Python Version: 3.11
• Biscuit 2.57.0 downloaded from CI artifacts

Thanks for opening an issue on this! otherwise this would've never gotten to my attention. Apparently arch linux installation is missing tcl/tk installation ig, so I will have to modify the build to bundle that as well, will share updates on this.

FYI: most Linux distros don't install tcl/tk by default, but that isn't related.

When you install PIL on Linux, it won't install the ImageTk part that makes it work with tkinter. You need to install it separately, most of the times with the distro's package manager (the package name is python3-pil.imagetk on Debian for example)
