Entering track customizer while in gameplay causes a soft lock

[LightningXCE]

Describe the bug While playing a song, attempt to enter the track customizer. Game will back out of gameplay, show loading screen, and then soft lock with the animated loading icon.

To Reproduce Steps to reproduce the behavior:

1. Play song
2. Enter Customizer
3. Stare at the kaledoscope

Expected behavior Customizer loads. Looks like it does attempt to load a new song inbetween but we never hit gameplay.
