I have no idea whats going on with this. This screen has never came up before. Help!

Reading the error box I would say there is a Lumetri or GPU effect on a clip at 67.7seconds into your movie that is causing the problem.

Test it by disabling it first and exporting (I know you want it) but you need to find other offending GPU effects later in the timeline as well.

Then if you feel you cannot replace them with non-GPU effects or do not wish to,  try changing the Renderer to Software Only and exporting again.
