Not opening default file explorer properly

[VimYoung]

Describe the bug
On trying to import the settings(called Backup) or importing the feeds and preferences as .opml, fluent reader is not opening the default file explorer correctly(in my case it is nautilus), no word is showing and boxes are showing instead of it.
I have the snap 0.7.1 version installed on my Ubuntu 24.04.

To Reproduce
Steps to reproduce the behavior:

1. Open fluent reader
2. Go to Settings > Sources and click on import
3. Alternatively move to Preferences in settings and click Backup in the bottom
4. In both the cases, the default file explorer open for choosing the location, it is not rendering properly.

Expected behavior
Nautilus should have opened properly, I think it is specific to Fluent reader as other applications open the explorer correctly if prompted to do so.
