Are you completely unable to start the game? Or are you having issues with a specific save? Can you start a new game fine or does that also not work?

Let's determine if it's mod-related. Please add the launch options -noWorkshop and -disableMods to the Steam and try starting a new city to test. It that doesn't load either, please attach the output log again from that attempt.

How To Set Launch Options

• Right-click on the game title under the Library in Steam and select Properties.
• Enter the launch options you wish to apply in the box (be sure to separate each code with a space). Should look like this:
  

  -noWorkshop -disableMods

• Close the game's Properties window and launch the game.

I did that before this thread and it worked fine. The challenge is I have not added any new mods since the last time it worked. I only added some assets that were reported missing and not deprecated. Were you able to glean anything from the Output file that was attached?

I hope you are able to assist. I ran it with Mods disabled and noWorkshop, it would not start up. All of the Mods I have, per the compatibility Report are fine. No Major issues. Please help get this game running again. Attached is the most recent output_log. Thank you

Disabling mods does not stop them from loading, as you can see in that log.
In your Steam Library right-click on this game and choose Properties. In the Launch Options line, paste this in there:

-noWorkshop -disableMods

Can you start the game then, and begin a new test city okay?
