I seem to have the same issue. I've tried your step by step and it still doesn't work. Not sure what to do. Had I known that this was an issue, I never would have upgraded my software earlier this week... Now I'm stuck and my deadline is tomorrow. Any way that anyone can help? Thanks, Natasha
There is a fix coming, but this touches on a lot of areas so resolving the root issue will probably end up in the next major release (as opposed to one of the smaller updates.)
Are you having trouble rendering videos? If you want help, email me and I'd be happy to do a screen share with you to get you going again.
It's likely that you have a null file preventing the render. Please follow the workaround in this thread and you should have no trouble rendering videos.
Export > Render video... brings not up a dialog for Settings but a message like the one in the image saying "Initializing Video Export" - and always get stuck in the middle no matter how simple the animation is. This is beeing reported already a lot around the internet. Please fix asap - we really need this feature. Thanks.
