Audio Skipping

This has been happening for maybe the last 6-8 months. I followed the same process before too, I download a video from insta, drag it into Pr in order to sync my clips but since recently there is the tiniest skip in the audio. If I refresh it, it could be at a different place in the timeline. It is also in the source monitor. It is not heard when I play this download in media player. 

I have tried changing frame rates, once in a while making a new sequence removes the problem, but sometimes it comes back again. Recently had Adobe Support look at that and somehow since then Pr is crashing even more so than usual. Any advice would be helpful.
