Audio Issues

The Issue is the audio for a project of mine is out of synch but in a way where its been stretched and cannot just be readjusted. I can fix it but it adds loud crackles to the audio and I am unsure how to fix it in adobe / media encoder so I can actually edit it and remaking it is not an option as the current project has already taken way too long to make to begin with

So is there a way to get rid of this audio crackle or have the audio be in synch in the first place?
