[Issue] File picker not opening

[yusshu]

Blockbench variant: Desktop App, cloned from master at e3ac34f
Operating System: Arch Linux, using Gnome as Desktop Environment
Issue: Can't open the file picker, I'm getting this error

also I found this issue, seems to be an Electron issue. I downgraded Electron to 13.4.0 and it works

Blockbench for Linux actually gets shipped with electron 13 (#1091), so this is a non-issue.
