Updated macOS Mojave from 10.14.5 to 10.14.6. Now Basecamp 4.8.4 cannot find maps.

Basecamp 4.8.4 (and Express) were working fine on 10.14.5 with my Edge 1000 & Zumo 396.

Then I updated to 10.14.6.

Express is still fine.

Basecamp detects the Edge & Zumo, but both are greyed out so they cannot be selected, and no maps are shown.

I tried deleting every garmin/basecamp/express file/directory under my home directory, and tried it again.

Express was still fine, but Basecamp still could not find the maps.

I tried installing Basecamp on an older laptop running latest macOS "High Sierra" 10.13.6 (can't be upgraded to Mojave).

Plugged in the Edge & Zumo, and their maps were detected just fine.

So it seems as if something has changed with the 10.14.6 Update.
