I’m having the same problem here…
My thoughs are that AE can’t handle too many audiotracks at the same time… or maybe it’s my computer that can’t.
So what i did was simply render the audio by itself and then import it to AE, turn off all the audios i was using before and use the audio i exported before.
That worked for me, hope it does for you guys too.
Also after trying like 12349128391283 times rendering it worked… i really don’t understand what is wrong.. but oh well
