Djay 2 crashes on startup (but free version works just fine!)

I’ve been using the trial version of djay 2 for Android for a few months, and I wanted some of the features I can get with the Windows (trial) version of djay pro, so I bought djay 2. After showing the djay logo for three seconds, and the main screen for around a fourth of a second, the app crashes. No error, nothing. I’m 99% sure this isn’t just device incompatibility because I’ve been using the trial version for multiple months with no issues. I have tried reinstalling the app and restarting my device, a Kyocera DuraForce Pro (E6810) running Android 7.1, with no improvement.
