I've tested it on Debian and Gentoo (Portage build), but not Linux Mint. Which version (numerically) of VotV are you installing, which version of Proton are you trying to run it with, and which package manager did you use to install steam?
Also, if you are an administrator on your computer, you may be able to `sudo chmod 777` the folder.
Hope this helps.

My assets folder was here: /home/[username]/.local/share/Steam/steamapps/compatdata/[id]/pfx/drive_c/users/steamuser/AppData/Local/VotV/Assets/
I was able to drop some music into the radio folder, and I can verify that it works in game on debian!
