Steps to Reproduce and Observed Behavior

1)Click "Import files" button.
2)Find the file you want to import.
3)Double click on it or click "open" button to import it.
4)It didn't import.
At first I was thinking it was problem with version from flathub, so I compiled the latest version. Still the same issue happens here. Then I was thinking, it's the problem with latest version, so I compiled previous one. The same issue still happens. Then I tried creating lump and using "Import" button. It gives error that it's unable to open file.

Expected Behavior

The file should be imported, but it didn't.

I had this problem when trying to import resources from a folder that had non-latin letters in its path. I was under impression that it was fixed, but perhaps I was wrong or it resurfaced.
