Additional Information​

I tried looking for a fix, and from the community page on Steam, someone had recommended to delete all files for the game and re start it. I had done this yesterday and afterwards could play; however, upon opening the game today - this issues.

I have not uploaded a save game, as it is when opening the game, after the launcher.

Such issues are almost always mod problems. Have you used the mod Skyve to check your mods are known to be okay and compatible with each other? You don't list it there.

Thank you for the report. It seems like it might be an issue with the mods you have installed.
Please try adding "--disableModding" as a launch option (https://pdxint.at/LaunchOptionsCS). This removes access to PDX Mods entirely, and if the game and a new save works with this enabled then the issue lies in the mods you have installed, and if you're unable to disable your mods in-game you can always do so on the web version.
 
me too
