Export page goes blank.
I have the same problem. I exported once since then I have a blank screen. Just did an update this morning and still the same issue.
There's a known issue where quitting Premiere while in Import or Export mode will cause those modes to be blank after relaunch. The workaround is to switch back to Edit mode, quit Premiere and relaunch. Import & Export modes should be functional again after that.
Still getting spinner after following Larry's steps above.
I have the same issue. All I see is the loading icon. It won't let me export the video in any way. The only way it shows is if there's no clips on the timeline, as soon as I add any clip it goes back to a loading mode.
