Playback suddenly slow, low-pitched

[James5E55]

So I started a multitrack project in Audition and I was doing a bunch of editing without any issues, and I saved and closed the project. I later reopened the project, and suddenly the playback is slowed and REALLY low-pitched. It sounds like the audio is lagging slightly behind where the playhead is on the project. I have reopened Audition several times and this issue is persisting. I have no idea what's going on. I don't know if it's an issue where somehow something has changed with the sample rate, but after looking at the .sesx file in a text editor it's definitely formated to 44100 hz and all of the audio files are also in 44100 hz. Would really like to fix this instead of starting all over.

Check and see what sample rate your audio interface is set to

Sounds as though a system sound has played between you closing the session and restarting it. This will reset your sound device to a very low sample rate, and if it doesn't reset then that's exactly the sort of thing that will happen. Make sure that all your system sounds are set firmly to 'off' (that's the No Sounds setting), reset your sound device to 44.1k and see if it's then okay.
