After app crashes launchctl is no longer able to start app

to add to the weirdness launchctl bootout gui/501/com.cirrusthinking.dollyappd Boot-out failed: 125: Unknown error: 125 no matter what I try I get failed errors on non legacy commands

I’d like to clarify what you mean by “app” in this context. Is this a program that displays a GUI, shows up in the Dock, and could reasonably be launched by the user by double clicking its icon in the Finder? Or something else?

The "app" is displayed in the Dock, its a GUI and a Status Bar item. We where able to resolve the issue by adding an extra key in the plist

<key>MachServices</key>
and
<key>Crashed</key>
<false/>

Still, the man pages are not enough to decipher all different options available and there is not enough documentation on the Apple developers site to well define the xml logic according to various MacOS version need. ....

OK. In that case it’s pretty normal for a crash to trigger the crash report UI. That’s what GUI apps do by default. AFAIK that’s a property of the app, not the way that the app was launched. You see the same thing if you run a GUI app from Terminal.

The standard solution is to mark the app as a UI element (via the [LSUIElement property][refLSUIElement]) but that prevents it from showing up in the Dock or having its own menu bar. I can still display a status bar item just fine.

I’m not sure what you mean by that. Please post the final launchd property list that you settled on.

Any alt option in xcode so that we can still have the app icon appear in Dock , even if it is a status bar item, but prevent the Crash Report UI ?

Not anything that springs to mind [1]. If an app appears in the Dock it’s a user-visible thing. If a user-visible thing goes away, you get a crash report. That makes sense to me.

With regards your launchd property list, why are you bouncing through open?

[1] You can play code-level games to suppress the crash reporter but that’s not something I’m comfortable recommending.
