I've updated to Media Encoder 14.3 and it's constantly crashing on export from Premiere Pro.
I've managed to work out that as soon as it gets to a scene that has Lumetri colour correction applied it crashes....not good
Does this happen on any scene with the Lumetri effect or just one? Have you tried doing a test of a new project with only a single clip that has Lumetri on it? If the test project doesn't crash try importing your working project into a new one. Alternatively, what happens if you delete then reapply the Lumetri effect to the proper scene (not just cut and paste, but reapply and correct from scratch)?
Also, if you export just that scene directly from Premiere does Premiere crash?
Sometimes stops rendering sometimes crash my Macbook Pro 2017 :S
Happens to me too on my MacBook Pro 13" 2015.
Just randomly stops rendering without any warnings, not even "stopped responding", but just freeze and stop for minutes, until you Force Quit it manually.
I Have a Imac 2019 with 64gb and ME crashes it..
