Multicam Crash

When trying to create a new multicam clip, FCPX crashes.

I have: Cam A, Cam B, and a .wav file. Both Cam A and Cam B will sync with the .wav file, but they won't sync to each other. Or rather, when I try to sync them FCPX crashes.

When I run Crash Analyzer I get the following explanation:

Audio Crash

This crash appears to have occurred while trying to play audio. This could be caused by a corrupt audio file, an unsupported audio format or a problematic audio device or driver.
Suggested Actions

In Final Cut Pro, try switching off audio waveforms.
Run a Comprehensive clean in Housekeeper to clear out the Audio Unit caches.
Clean caches in System Toolkit to clear out additional audio caches.
Use Corrupt Clip Finder to locate any corrupt audio files on your timeline.
Disconnect external audio hardware.
Use Plugin Manager to disable all non-essential audio units.
If you are outputting to a DV device such as a VTR, consider routing the audio from the soundcard to the audio input on the device instead of through FireWire (you may need to adjust the Frame Offset in System Settings > Playback Control in order to maintain synchronization).
Relevant Line

Thread 49 Crashed:: BGTask: FFMultiAngleAudioSyncTask Dispatch queue: NSOperationQueue 0x604002833300 (QOS: UNSPECIFIED)

I tried all its suggestion to no avail. Any advice? Thanks!

Sounds like you have a piece of audio in there that's an unsupported or possibly corrupted format. Try doing a version without any audio files.
