17.3 refuses to start.

Cannot find a solution to my specific problem, so opening a new thread. Apologies if I have missed a fix.

Originally had version 16 which worked without issue.
Overlayed 17.3 and I would get the first screen, which then closed.
Removed all traces of Kodi and reinstalled 17.3. Problem remains.

This is not the Addons27 issue.

Set the debug switch manually, and below is the output of the Log file:

@Karellen- Log File Removed

Hope someone can help, thank you.
