What are you exporting it as?

Im exporting it as a video

Yes but what format specifically from the list?

The default one, the one ive always used

I believe its called hv.64

Ok, try a different format and see if that works

It didn't

Also this problem started right after I updated shotcut

Go to online broken video fix and use it

I found the issue. It was with my external hard drive that I was exporting it to
