V17 wont run after upgrade from v16

Hi, i have been using Kodi version 16.1 for a couple of weeks, finding my way around. After feeling comfortable with this excellent program i thought that i would upgrade to v17.1. Herein the problem lies …

After the installation/upgrade Kodi refuses to start. if I ‘roll back’ to version 16.1 everything runs as before.

I have attached the Kodi.Log file as requested, and any help in this matter would be appreciated.

thanks
