I installed the App (v3.7.1) on a /e/OS v3.1 A15 GSI and could record a sample.
The app draws a spectrogram, I can select a part of it, do audio replays. It won’t crash.
Apart from the repeating PackageConfigPersister warnings (that I see in my logcat too), the only Error class lines in your logs (that I do not see on my device) are:
E AndroidRuntime: Process: com.labs.merlinbirdid.app, PID: 6830

I’d send the stacktrace to Submit a ticket : Help Center and ask what createFrequencyDataBuffer() can fail on. Naively: did you grant it the microphone permission? maybe some audiosink settings, recording frequency (khz)?
You have a FP5, I’d look for audio bugs in the bugtracker.
