Photoshop constantly not launching when trying to migrate a Light Room Classic edit into PS

[Lee Repass]

Since the latest updates this is what's happening. I have no idea what's going on.

Then sometimes I may get lucky to edit in CameraRaw or I may just look at a Black Screen. Heeellllpppppp!

Could you tell me which image format you are using?
What is the version No. of LR and Ps?

When the 'link' between Lightroom Classic and Photoshop has issues, one of the first things to try is this:
1. Use the Adobe Creative Cloud application to uninstall both Photoshop and Lightroom Classic and when asked, keep preferences. 
2. Install Photoshop first, then Lightroom Classic. The order is what is very important here.
Better?
