This error can happen when Beat Saber is not able to read the save file. There are a few things you can try which may fix the issue, one of these would be restarting your PS4 or rebooting your computer and then loading up Beat Saber again. The other thing that might temporarily help with this problem is deleting any saved game data from within Facebook or Steam as sometimes it will cause errors like 0x80004005 if another account has been using old files in order to get around permissions issues for example on Xbox One consoles.
