Firefox crashes on file dialog opening

Since a few weeks every time I try to open a file dialog on Firefox it completely crashes and my xdg-desktop-portal-gtk services crashes as well with a core dump.

I cannot reproduce this on Chromium or other software making use of the same xdg portal.

I’m using sway as my DE and here is my NixOS config: GitHub - jocelynthode/nixos-config: My NixOS configuration

Any help or hint on where to start investigating to determine what’s causing this issue would be appreciated :slight_smile:
