Thank you for the feedback. Is it on all the audio or just a specific track/moment? I mastered all the music with quite a bit of headroom, peak limiters and used a loudness meter, so the peaks should not come from the files. But maybe, if it is just a certain point, I can check and see if it is indeed in the audio and I indeed missed something.
I recorded a short video with the music messed up https://streamable.com/fhmzia
