Sound offset after export

Hello,

I work as an editor for podcasts and so far I have never encountered any problem when exporting. However, for some time now I have systematically had the same problem, no matter what project I am working on: the audio is completely out of sync (a few milliseconds added to each new clip, which is getting really weird) on every clip.

I tried to export on Media Composer, but the problem persists. What is even weirder is that after exporting, it is even my project/timeline that becomes out of sync, while everything was normal before exporting. I am working on a Mac 2022 M2.

Here are the files I am using. If it can help, I am attaching the audio track as well as one of the video tracks.

Thank you for your help.
