Is this happening only in Premier or with Media Encoder too?

try to delete render files from sequence or export to another format.

giving more info will help us help you better:

premiere pro version - project and sequence settings - file type - export settings etc...

1. In your Sequence, select Sequence > Render In to Out to render the clip. When you export, open the General section and enable Use Previews.

2. If that doesn't resolve it, open Export Settings, and under Video, click More, then set Encoding Settings to Software Encoding.

3. If that still doesn't work, try the same settings again, but choose Send to Media Encoder instead.

It very much sounds like you may have a corrupt video file in your timeline.

You may want to download the free app “Handbrake” and try converting file to a new version and then bring it back into Premiere and see if that helps.
