[2020] Game crash when launching a save

We'll need the files in the folder the error mentions to see what happens. You can find it by going into your games Library on Steam, right click on Cities: Skylines, select Properties, go to the Local Files tab and click Browse Local Files.

Then grab the files in the folder from the last crash and post them somewhere. We can't attach files here on Steam, so it will have to be some file hosting site or cloud drive. This guide as a few suggestions for places which are free to use.
