Win 7 64 Kodi 17.1 wont start after upgrade

Hello all,

as the Title says, i cant get Kodi 17.1 to start anymore after upgraded to 17.1.
The versions before worked fine.

Tried the “addons27….” method and it worked partially as i am now getting another error at the bottom of the log.
Please find log at https://pastebin.com/J0H4qFvf

When i start Kodi now, it sometimes justz shows the splash screen doing nothing, or it shows the splash screen with additional message “database migration in progress” which i can keep running for hours ( i tried 4 hours once before i lost confidence).
In both cases Kodi doesnt start further.

Oh and i dont have a second graphics adapter in my desktop PC.
Btw, had the same issue earlier when i tried the 17.1 RC4, then i moved back to 16, so i could work with Kodi again

Hope you can give me a hint, i miss my Kodi. 😉

If you need further details pls do let me know

Thank you in advance
