I found the solution here:
https://forum.level1techs.com/t/gtk-applications-are-super-slow-at-startup/166540
All I needed to do was to remove *xdg-desktop-portal* package:
*sudo apt purge xdg-desktop-portal
sudo apt autoremove*
Now GTK apps open up normally again and also Dropbox tray icon works
great again!
