After Effects White Box Crash
I'm working on a complex project, where I've had to duplicate parts of the projects in separate files and then import the other projects back in to the main project to combine them.
Getting a very strange crash when I open some comps in the imported projects. It will just give me this white box and then become totally unresponsive until I quit AE. The white box affects my whole system - it shows when I'm in other applications. It doesn't trigger a crash or error message at all. Sometimes it comes back to life, other times I don't get the crash and can open the comp (not very often). Cleared all caches, didn't do anything. Not using any plugins.
Any idea what might be causing this?
