Very low FPS because of AudioManager

2 hours ago I had a solid 90fps in game, but for some reason the fps started dropping really low (<20fps).
And I opened the profiler and saw that the AudioManager’s “UpdateAudio” method uses 95%~ of usage.

The weird things is that I don’t use the AudioManager at all. Apart from the caraudio from the standard assets. I tried deleting all of the GameObjects from the scene but it didn’t help.

What I saw in the profiler

I fixed it by restarting my computer. It was a weird bug.
