Sony a7iii XAVC S h.264 export audio/video not syncing

When I export my sequence as (h.264 - high bitrate) my audio/video isn't synced; the audio is sped up and the video is twice as long. It appears synced in the sequence timeline. When watching the source clips in windows app Movies & TV the audio/video is synced and clips are the same length as in my sequence timeline. If I export as an (MPEG4 - 3GPP 352 x 288 h.263) or (AVI - NTSC DV) the audio/video is synced and video is intended length, but video quality is not as good as h.264. Hopefully somone will be able to tell me what I am doing wrong. I tried reinstalling premiere and that didn't help. I shot the video in XAVC S HD using a sony a7iii. I am using premiere pro 2020 cc v 14.3.

If you turn off Hardware Encoding does it work? I've seen this issue posted once or twice before but I can't specifically remember the fix. Hopefully someone else also chimes in.

 

I would also go into your Preferences>Audio Hardware, and make sure your input is set to none.

I put the clips on my friends macbook pro and it exported fine as h.264. Could there be some setting that is saving in PP even when I uninstall/reinstall? Someone please help, I am very confused and tempted to just buy a macbook.

    Hey Phillip! That worked! Any idea why the audio may be going out of sync with hardware encoding on rather than software encoding? This issue popped out of nowhere for me.
