@Timothy-Donovan Hi, more info is need, 👍

What software are you using? this is the Magix forum, Magix 'Exports', but Vegas 'Renders', so depending on your software you might need the Vegas forum instead https://www.vegascreativesoftware.info/us/vegas-pro-forum/

What is the error msg? pictures can be uploaded using the arrow button next to the smiley at the top of a new comment.

Does it start rendering & then stop or does it just not start?

Rendering failures that stop part way through can be down to a damaged file on the timeline, try breaking your project timeline into pieces & render the sections separately to see if you can narrow down to the damaged file,

It could be software or a hardware issue so - can you click your icon at the top of this page - My Profile & fill in your Signature with the full name of your CPU, GPU & amount of RAM, also inc the Windows & Magix version, this will then show at the bottom of your comments,
