Snaps show squares instead of fonts

I need help. I don’t know what happened but starting today every installed snaps shows weird squares instead of fonts. When launched via terminal the snap store shows several errors (see image below). I’m running Pop!OS 20.04 LTS and snapd 2.45.

Ok, I found a solution here: https://askubuntu.com/questions/1224125/font-characters-displayed-as-squares-in-ubuntu-18-04

rm -rf ~/.cache/fontconfig && sudo fc-cache -r -v

Thank you anyway :slight_smile:

For completeness can you provide the output of dpkg -l |grep fontconfig ?

@mborzecki Following up here, I maintain Beekeeper Studio and I’m seeing this issue:

  1. Freshly install Fedora 32 Desktop (Virtualbox)
  2. Install Snapd
  3. sudo snap install beekeeper-studio
  4. Open Beekeeper and try to open a sqlite file

Result: Missing fonts in the file picker.

This is a 100% fresh install. I also tried the AppImage version of Beekeeper, which works totally fine.
Is my app missing an interface or something? Here are the interfaces connected:

[rathboma@localhost ~]$ snap connections beekeeper-studio
