I have not experienced the issue you’re describing on either my Mac or my Windows machines. I’ve been using CC 2015 in my freelance production without issue.
It’s possible that something in your setup is triggering a bug of some kind, but without knowing more, it’s hard to say.
There is an update coming out next month for AE that is meant to be fixing a LOT of bugs, so if you don’t have time to troubleshoot now, just use CC 2014 for the time being and try CC 2015 again after the update releases.
