Development on Catalina, Fail

My signed (thanks, Miyako) and notarized app (17.3), runs on Catalina.

However, the development environment does not run on Catalina on my test machine. A freshly downloaded copy of 17.3 won’t run on Catalina.

Has anyone heard when 4D will get around to signing and notarizing 17.x to run on Catalina?

According to this > and what Thomas Maul said, try with the latest nightly builds of v17.
