Q: Why desktop icons in Ubuntu 20.04 don't work properly? The problem started using 18.04. I may have accidentally changed some settings. All desktop icons, including the one that I have created, and the ones automatically created by applications, changed their look. They are all the same. Setting a custom icon is not possible anymore. Also, they won't launch the same way, permission is needed every time.
I upgraded to Ubuntu 20.04, but the problem got even worse. Now .desktop files work even more complicated, no custom icon, and even sqlite3 files look different.
This how it looks on the Desktop:

And in Nautilus (.desktop is the same):
