libdav1d.so disk write error

I seem to be getting a disk write error every time I try and launch a game. An error occurred while launching this game : disk write error - /run/media/deck/546B-6466/steamapps/downloading/2805730/files/lib64/libdav1d.so Running bazzite gnome fed linux 40.20240609.0 on Lenovo Legion Go. In further testing, it doesn't seem every game is affected. I can launch some games regardless of where they are installed, but reinstalling doesn't help. I thought it might be a proton issue as when I try and update from Steam I get a disk write error. Issue seems strange because I have plenty of space and can even install new games. I've tried to go into the games and uninstall the proton files, then tried launching them again and get the same error message. I've tried totally uninstalling and reinstalling a game, still gets to an error. I tried installing Proton with protonplus, and it seems to install fine, but not anywhere steam must be looking. What it feels like to me is that maybe it tried to update proton or something at sometime, and it failed, but won't remove it fo process the necessary update, causing proton to not work as a compatibility layer. I'm still fairly new to Linux, but am figuring things out pretty quickly.
