Rekordbox 5.4.3 does not open, post upgrade from 5.4.2

Hello,

I recent upgraded from 5.4.2 to 5.4.3. All was working shortly post update, but following a few reboots (and possibly a recent Windows update), rekordbox fails to open its main window.

Further examination shows that the the rekordbox process is running, and when the program is launched, a box appears saying "Reading tracks", then disappears. Nothing else is displayed.

I have tried, uninstalling / reinstalling, backing up and removing the master database all to no avail.

Any help offered in getting my rekordbox up and running again, would be greatly appreciated :)
