EXR files are bugged in 25.4

EXR file alpha channels are not being rendered correctly. Some frames will have empty alphas, some frames with only show a small strip at the top of the frame. The same projects work fine in 24.3.2.

If you're able, please try the AE Beta 25.6 builds available in Creative Cloud Desktop. There is a fix for the EXR issues we are testing.

I tested it on a few files, and it does seem to be working correctly on the beta.
