So is the app crashing when you try to start it up a new "feature"?
2019 iMac 5k
big sur 11.2.3
Premier 15.1 fails to start
Premier 14.9 runs just fine
Sorry for the problem. Can you give us more info on the system and OS? Any warning dialog boxes at launch? Does it hang at a certain point, like when plug ins are loading? Have you tried removing your plug-ins and relaunching? Are all your plug-ins certified to run in 15.1 or later? Have you deleted all media cache? Have you tried trashing preferences? These are things I would try if the new version is not launching.
Let us know.
I'mm trying to reply with details, but somehow the forum wont let me post.
Sorry about that. Let me know if you are still having trouble with the post.
Sorry, I didn't hear back from you yet so I'll branch your post to the main forum. Let us know if you need added assistance or if you solved your issue (and how you did so!).
Thanks so much and sorry for the hassle.
