Can't access PS from LR - ??

No idea what happened here, but I can no longer open up a shot - any shot - from LR to PS. The menu option is grayed out and Ctl E doesn't work either. Any ideas? Both programs are latest release.

Go to the external editing tab under Preferences and make sure the top part of the dialog box is filled out correctly.

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 of the product installed is what is very important here.
Better?

Thanks Andrew. By doing that do I get to keep my third party filters, brushes etc., intact, when I reinstall?

That should be kept.
That said, always save them:
