Export Issues with Premiere pro 2025 (and beta)

Hi there !
I exported this video once and noticed that had no sound, so when I tried to export again this started to happend: trying to export a 16min long wedding video - without any crazy effects or color grading - and premiere stops at 100% encoding, or sometimes even at 0%. It doesnt show any errors, it just stops and then when I cancel and try to exit the app it crashes but also without showing any errors.

I've tried doing a copy of the project and even create another project with the same sequence and files but the same thing keeps happening. I've also unninstalled both versions of premiere (pro and beta) and keep having the same problem. I've cleaned media cache already.

I have a macbook pro m1 from 2021 - never had any problems with this.
