"Undefined is not an object" I kept having this error

[anh.ha12]

So everytime when I apply a transition, I kept having this error, and it slowed my whole project down, even when I moved the whole project to my local drive on my Mac, the same error keep happening. Does anyone know how to fix this? It's really effecting my workflow and timeframe. Thanks

Hi there,

We're sorry to hear about this. We would need more info to diagnose the issue properly. Please let us know the version of Premiere Pro that you are using & the system specs? Also, does this happen with any specific transition or all of them? 

Thanks,

Sumeet
