Do you know how to get to appdata? If not, I'll explain how, if you do then ignore all this. It's not in the actual game folder, it's a common outside directory for games and other software's saves and settings and such so that they don't get accidently wiped For some reason it's a hidden folder by default, so even if you know the directory you can't navigate to it without using a command or changing a setting. There's two popular ways to get there, I'd recommend doing the first, it's takes a little bit of setup but it's not complicated, and makes it ridiculously easy to access in the future but 2 is effectively instant and easy too:
Option 1: Open file explorer, go to the "View" tab at the top, and on the far right of the tool bar that opens, there will be an options panel. Open the options, and go to the "view" tab in the new window that pops up. 6 option down *should* be "Hidden files and folders"- select "show hidden files, folders, and drives", hit apply, and close the options. After this, you can navigate to the appdata manually quite easily and pin it to the quick access bar on the left. Simply open the drive windows is installed on in file explorer, and go to Users>(your username)>AppData (it will be grayed out to show its normally hidden, but is now shown and accessible.) Right click it and near the top should be "pin to quick access", and you can now instantly access it from the left any time you're in file explorer.
Option 2: Simply type %appdata% in the windows search/cortana bar and hit enter- This will take you to the WRONG folder for some reason, not actually the appdata folder, but it is within the appdata folder, so you can simply click "appdata" from the navigation chain in the address bar, or hit the up arrow beside the address bar (the shortcut is alt+up if you want to do it even faster)

From there it's as we said, there should be all your folders for saves and assets and such in appdata>local>votv

If you knew all of this and running the game as admin did not fix the issue, it's definitely a bug, but you can probably build the folders yourself, they're not super complicated and there's no special files in them that wouldn't already be generated for the game to even be able to run.
