Getting blank after editing

After hour of editing my video still getting some blank and no audio, after export to my files?
Can anyone help, Try the fade in and fade out but no luck!

Do you happen to have the “use hardware encoder” option on in the Export options?

If so, turn it off and try exporting again.

Also, in the future, if you continue to have problems with an issue you made a thread out of already, you can just post it in that existing thread: Blank after editing?

No need to start another one
