most feature invocation is delayed before active
I have downgraded macOS Catalina to macOS Mojave. Having trouble with System Preferences crashing when checking for software update. I used a macOS Mojave 10.14.6 installer USB 3.0 drive. After successful installation, I attempted to update the macOS Mojave security (and Safari) updates. The update failed and upon a user-induced reboot, System Preferences app crashes. I am open to suggestions. Thank you in advance for your assistance. I will be happy to provide additional documentation!
