Bug: Can't render H.264 after Premiere Pro CC2019 13.0.1 update
It will make a zero byte mp4 file with an small xmp file with 66kb, it didn't crash , but fully renders and can still edit further after, but also does the same with media encoder. Yet in CC2018 it still can render H.264 files. Yet CC2019 can render out other codecs without issues. Have restarted my computer a few times and still this issue occurs and not sure how to fix this.
