Hello, I’m trying to make a snap of my electron app. However, when I run my app, console.log appear, but GUI is never displayed because app crashed with this error: GLib-GIO-CRITICAL **: 19:43:37.669: g_settings_schema_source_lookup: assertion 'source != NULL' failed

My snapcraft.yaml

name: tess
base: core20 # the base snap is the execution environment for this snap
version: '0.5.4'
summary: Single-line elevator pitch for your amazing snap

  This is my-snap's description. You have a paragraph or two to tell the
  most important story about your snap. Keep it under 100 words though,
  we live in tweetspace and your description wants to look good in the snap
  store.
