[GNC] Gnucash 4.0 doesn't launch on MacOS X 10.15.4

[will at theprescotts.com]

I have:

Gnucash-2.6.1-1
Gnucash-3.0-1
Gnucash-3.4
Gnucash-3.10
Gnucash-4.0

All installed and 4.0.2 works without deleting any of them. Mac OS 10.15.5. For whatever that is worth.

Agreed, it absolutely should.  Alton's theory was that something about
having both installed was confusing something.  All I know if it didn't
work until I deleted my old installation.
