Any fix for export failure?

Hi, I know that Rush is being discontinued so I don't have much hope, but does anyone have any way of getting projects to export? Whenever I try to export a project (either by clicking "Share", going File > Share, or using the Ctrl+E keyboard shortcut), Premiere Rush freezes and will not respond. I end up having to quit it in Task Manager. I've had this problem for a few weeks now, but it would eventually start working after a few quits and restarts - now, no joy at all. I just want to get my finished projects out so I can move to a software that actually works and is supported! Thanks in advance.
