Snap version of keepassxc 2.3.4 fails to open text file attachment. I can open this same text file attachment on macOS with keepassxc 2.3.4

Expected Behavior

Should open text file in a separate program

Current Behavior

All I get is an error message:

Steps to Reproduce (for bugs)

1. Install keepassxc via snap
2. Attach a simple text file via add attachment
3. Open same text file

Context

This feature is important for recovery codes
