I've got a similar problem.
Game version is 3.0.226.993. My PC has a Ryzen5 2600X, Asus RX 6600 XT, MSI B450 Tomahawk Max, Windows 10. I own the GOG version of the game.
I read through the technical support thread and tried out those tips, but none helped.
When I start regularly (with the launcher) the Definitive Edition the launcher starts, goes half way through and then just crashes to the desktop. No message displayed. When I choose the DoS 2 (Classic) version the game runs perfectly.
Using the EoCApp.exe workaround didn't help either - crash.
I own the game for a couple of years and it used to be playable with no problems at all.
Any help would be appreciated.
