After the update to 14.8 my project files would crash while trying to open. Even one I had been working on only 2 hours previous once closed it and then it would not open. I started a new project file and imported the old one, everything worked fine while open but once again once closed it kept crashing on reopen. I spent 2 hours with Adobe support controlling my machine, had all my preferences reset for Premiere Pro and then the Adobe CC suite. I was told it was a project specific issue even tho it was happening to multiple projects and 2 of my collegaues were having the same issue. I was also told it was a server permissions issue but no permissions had been change, everything was working fine only a few hours previous and a Project on my desktop was having the same issue. The only thing that solved the issue for me was to roll back to an older version of premiere and everything worked fine again, so my advice is don't waste your time with support as they clearly don't know about the bug or don't want to admit it, so just roll back to 14.6 or .7 and it should solve it.
