Premiere Pro crush when to export

A new build of Premiere Pro Beta has been posted to Creative Cloud that should resolve this crash when exporting. It will be shown as version 14.3.2.27

I'm sorry this is happening. Good news in this case is we've isolated what is causing this crash and a fix will be available in the next build you see for Premiere Pro Beta. Keep an eye on the Updates section of the Creative Cloud app. Thank you.
