Edit Favorites freezes & long first-start delay

Windows 10x64
Directory Opus 12.27x64

I have problems with Favorites.
When I'm trying to edit Favorites with Dopus GUI it freezes. I have several unreachable UNC paths in my Favorites so I can suppose they're the reason. And also I have very long first start of Dopus.
I would like to troubleshoot this issue. And also is it possible to edit Favorites links without Dopus GUI, for example with Notepad++?

Yes, they are here:

/dopusdata\ConfigFiles\favorites.ofv

Thank you very much!
