Arduino-IDE will not open [solved]

Development Tools IDE 2.x
1

This morning I turned on my laptop and clicked on the Arduino shortcut but all that happened is that the white page with Arduino IDE in the top left hand corner appears with the round Arduino emblem zooming in and out. It's been doing that for over a 1/2 hour.

I un-installed IDE 2.0 then reinstalled but the same issue arises.

I have disabled the Firewall (Bitdefender).

Could this be anything to do with IDE 2.0.0-rc3 still showing on the Windwows app list in addition to IDE2.0.3?

My IDE 2.0.3 gets stuck some times (64 bit, 2-core, 4GB RAM - and still "not fast enough"). Resize the white box, either to full screen or windowed to see if that wakes up the app handler.
