Movie Render Queue Object ID freezing

I’m using 4.27 but can’t render out Object IDs as it freezes at the end of the rendering process. I can render EXRs fine but as soon as I add an Object ID pass to the render settings it doesn’t work and I have to force quit the app?!

If I render any other file type with Object IDs it works but this is not ideal as I need an EXR for all the mattes.

I’m rendering one frame if that helps?

Is it possible to render out in a different format, that works, and then convert those images into your required exr format?

I would suggest reporting it as a bug
