Failed to load sound, unsupported file format?

My game was working fine until recently when a majority of the sounds started erroring right when the game loads.

ERROR: 16:34:59.801 - Failed to load sound rbxassetid://1836102253: unsupported file format

This happens for a lot of different sounds in my game, but not all of them. Is anyone else experiencing this error or know why it is happening?
