Hello ehays,
We're happy to help research possible solutions. Just a few questions to get started looking into solutions. Are all your Mac's running the same macOS version?
Have you tested the issue in safe mode? If not, that's a great place to start since this process will disabled startup items, login items, system extensions not required by macOS. If you're not familiar with the process, check out the link and steps below for full details.
How to use safe mode on your Mac - Apple Support
How to use safe mode
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
1. Shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.
3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”
4. Log in to your Mac. You might be asked to log in again.
Intel processor
1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac.
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.
Once you've tested in safe mode, reboot and test again under normal startup. The reason for this, is that safe mode will also run a process similar to First Aid in Disk Utilities and may correct the issue.
Keep us posted on how it goes.
Best regards.
