Do you have mods? You can only have one core mod at a time. uninstall CAW and try the game. I you moved the user files and still have the problem that indicates an issue with the basic installation. What antivirus do you have?
The only mod that I still have isntalled is the hidden skills mod. Looking at my computer now, I remembered that I did already uninstall CAW, just because I couldn't be bothered with making worlds until I'd become familiar with all the controls and stuff by wathcing videos. I've got Norton Antivirus on my laptop just now, and it does a lot of frequent scans. It's always told me if any downloads were safe or not. I don't think I touched any of the User Files, but I'm not actually sure what those are. I haven't move any files around that I remember of, though.
Can you disable the antivirus while playing the game? I use Microsoft Security Essentials and have no problems and it works well and it's free. I am unfamiliar with the hidden skills mods so I don't know how that effects the game or needs to be updated when there is a game patch. Did you try resetting the game? Here is a link - reset game This will tell you if user data is causing the trouble or the game files are corrupt.
I tried disabling the antivirus, which didn't work. My computer already has Microsoft Defender installed already, but I got Norton as a free trial. The Hidden skills mod is used by a lot of people, and doesn't cause any problems that I know of that stop the game from working. I tried resetting the game following the instructions, but that didn't work either.
