reset your preferences -
(or remove Win: C:\Users\<username>\AppData\Local\Adobe\Animate CC 2017\ and
Mac: /Users/<username>/Library/Application Support/Adobe/Animate CC 2017/ and
That didn't work actually, it's still crashing.
1. did you successfully reset your preferences?
2. is that the only file that crashes animate?
Yes I did! Or at least I deleted the folders you mentioned above.
I'm running MacOS High Sierra and running Animate CC2018
does it only crash with that one fla?
Apologize for the delayed response as I was away on a long vacation. Are you still facing this issue? Also, like kglad asked you, are you facing an issue with just this one file?
