VLC won't open mp4 files in my Cryptomator revealed vault

Is there a process to open mp4 files that are stored in a Cryptomator vault using VLC? With the vault revealed, I can right click mp4 files and open them with Parole Media player but not with VLC. I get this error message from VLC -
VLC is unable to open the MRL 'file:///home/dell/.local/share/Cryptomator/mnt/****
