Hi everyone,
I've been having a lot of issues lately with rendering timelines that have Magic Mask. The error I get is this:

This is usually how I get the error:
I work on a 1080p timeline and use the magic mask on certain scenes. Everything exports correctly. Then I change the timeline to 4K UHD and re-render the magic mask. Then when I try to render out the video I get this error.
Certain actions have helped fix this problem:
1. Clearing the cache
2. Making sure there is enough space for the Resolve cache on the external SSD that I'm working with
3. Deleting the magic mask node, adding it again and re-rendering the mask
But this doesn't always work. On a current project that I'm working on none of these actions work and it's really annoying...
Is this a bug? Am I doing something wrong? Is there anything else I can do to fix this?
All help and suggestions are welcome : )
P.S. I'm using Davinci Resolve Studio 19.1.4 on MacOS Sequoia 15.3.1, M2 Max processor.
