macOS Mojave update 10.14.6 (18G6032) "You shut down your computer because of a problem"

[nkl984]

Hi guys!
Since this update to macOS Mojave update 10.14.6 (18G6032) on my iMac Pro everytime I start the computer I get the dialog box saying that "You shut down your computer because of a problem". I have contacted Apple and they asked me to reinstall from time machine backup and the probem was still present, also factory reinstall mac OS High Sierra and the problem was still present.
I am currently running the Mojave 10.14.6 (18G6032) latest version and still having the same dialog box when starting the computer but if I choose "Quit Safari" before shutting down the computer when I start it the dialog box dissapear.
I'm wondering if any of you here experiencing this issue.
I think this is a Safari Version 14.0 (14610.1.28.1.10) related issue. Any ideea how to fix this?
Note: The iMac Pro is working normally and I get NO restarts. Just when I start the machine I get the dialog box saying "You shut down your computer because of a problem. If you want to open the applications that were open when you shut down, click Open. If you do nothing your computer will continue to login in ... seconds.”
Attached Diagnostic Reports maybe someone can help me. PS: (I'm not a IT guy, I'm a musician)

Also the "Send to Apple" report here maybe that helps:

Same issue here on Macbook Air 2018. Only if manually quit all apps this doesn't appear. Looks like the system is shutting down too quick to correctly close all the apps or something like that?

I really don’t know but as apple customer care advised, I tried to reinstall mac os, also format and factory os reinstall and the issue is still present. I guess after the 005 Mojave update the firmare updated also and the issue persist. Maybe updating to Big Sur will fix the firmware but I cannot do that as my machine is used as main computer in my music studio and I cannot play with new software and be a guinea pig apple tester. 😡

I got the same message today when I shut down my Mac Mini without closing all windows due to a power outage and not wanting to use up the battery in the UPS. This was the first time I have seen that. I usually close all open programs before shutting down or restarting.
