Hi @ProtoJohnson  ,

Sorry for this problem. We have done some export improvements in the latest beta builds. We expect exports to come out without glitches now. You can download the latest Premiere Pro Beta build from Creative Cloud --> Beta apps --> Premiere Pro (Beta)

Please try and let us know how it goes in the beta build. If you still see this issue in beta builds, please share your original footage & export settings. We will check it at our end and take quick action.

Thanks,
Mayjain
