I am unsure why, but lately every time I try to render it just gets to 99% and never completes. I've tested it a number of times and it'll sit there for hours (no literally). Additionally, everytime I want to export the same thing happens, except the entire computer goes into a bunch of crazy colors and patterns and then shuts down and brings me back to the log in window.
I have a big video for work due and really need help with this problem. I am using Premiere version 22.0, on a MacOS Big Sur version 11.6, and I am editing with black magic footage.
