After Effects can't continue: Roto Brush & Refine Edge plug-in generated an unexpected exception.

I was able to resolve this by importing the corrupted project into a new one, then sneaking my way up to the comp that causes the error, the one with the rotobrush effect in it. Then i deleted this effect. Had to redo the roto brush though, but didnt lose the rest.

I have the same problem...

Found out what it was. It was being caused by Premiere being linked to After effetcs using the linking tool premiere provides in software.....Even if I closed out premiere it was till linked behind the scenes and cauging crash.....I had to render out the original file from premiere as its own copy then restart the whole after effects edit from that file in order for it to woor....pretty frustrating and cost me a lot of time

I am having the same issue.....Roto crashing with the same error message.

I have faceing same issue., but i try this steps but i can't solving the issue., what i do??

That error can be frustrating, but let's troubleshoot it together! Here are some steps you can try:

1. Restart After Effects – Sometimes, a simple restart can resolve temporary glitches.
2. Update After Effects – Ensure you're using the latest version, as updates often fix bugs.
3. Clear Cache – Go to Edit > Purge > All Memory & Disk Cache to remove any corrupted cache files.
4. Disable GPU Acceleration – In Preferences > Display, try switching off GPU acceleration.
5. Reinstall After Effects – If the issue persists, reinstalling the software might help.

Hi, I have the same issue. I can't open my project. 
I have reinstalled AE and runned in safe mode, nothing change. 

The thing is, this morning when I opened the file, there was a warning that rotobrush had some error that I don't know about, and the same file last night was fine. I hope someone can help me. Thanks.
