Roto Brush crashes AE

The Roto brush tool crashes after effects quite often in V22.6. It's becoming unuseable. I tried opening new AE files with just a single clip and click the roto brush once & it'll crash; I've tested it with different clips, & with Mercury GPU acceleration (CUDA) & Mercury Software Only

What is the file format? MP4 files are problematic. If tht is the case, try to transcode into any other format. like Quicktime ProRes or DNX.

What is the size of the original footage? Have you tried to convert it to a proxy format?
