Configurations not saving

The save button under Save & Load does not save the vehicle, is there any solution that doesn't require restarting? I don't want to restart the game and have to remake the config.
If it helps, pressing the save button zooms the camera in and takes a photo of the car, but the car does not show up in the vehicles or Save & Load menus.
No mods are installed, and the setting to show custom cars in the vehicles menu is turned on.

 

Sorry for the late reply, the support ID is 79451.
Edit: is there a fast way to fix the userfolder problem thing? My game has been open this whole time
Edit 2: It can definitely access the folder, the .pngs are there, every time I try to save it only saves the image.

 

I'm necroing this because I still have this problem, I've been saving my configs in text files
Please god help
Reinstalling, verifying integrity, and completely deleting the documents folder did nada
