I get this error when I export my project in Adobe Rush on PC.
-I've tried different export quality. Interestingly, the Error code occasionally changes to Error Code 3, but most of the time the code is -1609629690.
-I've tried deleting the entire timecode that the error states (even going far as deleting my entire video except for a one second clip).
-For this same project, I was able to successfully export using the identical export settings earlier in the day. The only thing I did after that first export was change the Range Speed of my clips to change my video to fast-motion. No other edits were made. But now I cannot export.
