Game Crashes After Start-Up Movie following 4.1 and 4.2 updates

Posted on Tuesday, August 10, 2021
I have purchased through Steam the base game and all of the expansions, civilizations packs, and ship packs and everything has been working for years without issue.  Recently, Steam indicated that the new 4.1 and 4.2 update was available and was being downloaded.  After the updates were downloaded, the game stopped working.  I can open up the game.  It will play the start up screen from Retribution with the Drath and Drengin then the start-up movie between the Thalian and Human and then before going to the game setup screen where you can load a game or start a new one it crashes and gives me the following error message:
Steam recommended I check the integrity of game files.  If now references four (4) files unverified.  I run the check disk and fix it.  I run the check disk again and it says all files are verified.  I then open up the game and the same issue repeats itself.  After repeated attempts at these solutions, I then uninstalled the game from my computer from Steam and then reinstalled the game twice but the problem still persists.  I am unsure if my older computer was made obsolete by something upgraded in the new updates.  Anyone with information, please assist me as I am unsure what else to do.
