Hello! I just got a crash report from Firebase with the following stack trace. I honestly have no idea what could be causing the issue and I was hoping someone might be able to point me in the right direction.The following line in the Main Thread Stack Trace seems like the most likely candidate:8 TrainCentric 0x104d85ca0 specialized MySound.init(url:category:) + 40 (Sound.swift:40)But line 40 of Sound.swift only allocates an AVAudioFile.try self.audioFile = AVAudioFile.init(forReading: fileURL.absoluteURL)I'm quite certain the file exists, and even if it didn't, I tested to see if I could get a similar stack by trying to load an invalid URL and the app did not crash because of the enclosing try statement for this line of code.OS Version: 13.3.1 (17D50)Phone: iPhone 6sCrashing Thread Stack TraceCrashed: AURemoteIO::IOThread 0 libsystem_pthread.dylib
