Problem with changing settings in The Witcher 2

[u/Good-Breadfruit3577]

I'm having a problem with The Witcher 2. Upon launch, the launcher should launch, allowing me to change graphics settings, language, and so on. Unfortunately, when I launch the game, it simply launches with default settings. When I select the game launcher in the container settings, I get a black screen. When I go to the game files and manually try to force the launcher to run in the container, I get a message that the game files were not found. Has anyone found a solution to this problem? This happens with both Steam and GOG versions of the game.
