Sequencer crash

Hello, I’m trying to capture a movie from Sequencer, and as soon as I click “Capture Movie”, the video preview window appears, but remains black, and Unreal hangs.

I tried creating a new project with a terrain asset, sequencer, and camera. Capturing a movie in that project worked without any issues.

I then tried going back to my problem project, deleting everything in the scene, then creating a new sequencer, camera, and terrain asset, and capturing a movie, but I still get the same crash happening in that project as before.

Lastly, I tried creating a new level in my tutorial project, creating a new sequencer and camera…and I still got the same crash.

So to summarise, it seems like there’s a problem with my entire project somewhere that’s stopping me rendering movies. I disabled the only additional plugin I had installed, and that also didn’t help.
