Unfortunately the live wallpapers did not play correctly, they started playing on the lock screen and then paused as soon I unlocked my device.
I've extracted the required png's and 60fps mp4's and repackaged into individual live wallpaper apk's which correctly play after unlocking.
Tested working on my 6T and confirmed working on many other phones.
Downloads including new live wallpaper from OnePlus 7 Pro 5G
Thanks to @RocketSauce83 for the base apk.
