The mysterious email : "Your Certificate Has Been Revoked"

The issue around CERTIFICATES and their RANDOM REVOCATION is one that I just can’t get my head around, as hard as I may try.

I’ve read “Certificate Signing Requests Explained” and most others that one would consider relevant and I’d like to say “I get it” except…I don’t. At least not well enough to prevent what I’m encountering.

I have a developer account (at the moment it needs to be renewed) and a dev team (me) that lets me do whatever in Xcode.

I’ve compiled several apps for macOS, each of which runs fine, for a time. Then, after a random interval of days or sometimes weeks I get the DREADED EMAIL from Apple that reads: "Your Certificate Has Been Revoked. You have revoked your certificate, so it is no longer valid", and they don’t!

Any attempt to start them generates the warning "[This App] will damage your computer. You should move it to the Trash."

Each needs to be recompiled with what is apparently a valid certificate courtesy of Xcode to get them to run again, which they do, until the next email from Apple shows up and they don’t.

Let me stipulate that I have done nothing overtly to revoke these certificates (6 revocations since April 22) nor have I done anything but use Xcode to automatically manage the creation of new ones.

So the ask: what I do I need to do to keep this from happening?

PS: I have read numerous places to ignore these emails which I have done without consequence. Only now after I am using several apps that I've created has this become problem.
