it seems like its happening just for me, but about 80% of the sound effects are giving me errors. I cant open them in the media player, and in Godot (4.3) they give errors that say they cant be added.
for example, the sounds: Cancel.wav, Confirm.wav, jump.wav can be opened and heard, and sounds such as: bump.wav, click.wav, crunch.wav cant be opened or used.
although from the sound effects i could hear they sound very good, thanks! ill use them in my game if they would work.
