We are having persistent issues opening projects that have missing footage. It seems to have popped up for us with CC2019 on Windows. If I try to open a project, especially one from an earlier AE version, and it has any missing footage, it takes an eternity to open. Sometimes over an hour. These are not projects that should take more than a few seconds to open. It behaves better when we try it on our one iMac here. Has anyone found this issue as well or found a way to fix it? It's a severe hindrance to say the least.
