Prores4444 + Alpha portrait formats compressed Problem

[BNP_01]

Recently, I've been rendering portrait formats compressed. However, this only happens when I select Prores4444 + Alpha from output format. Does anyone have an idea what the problem could be?

When I render "uncompressed" everything is ok.

Same problem on Mac M1 Max  and Intel. Mac os 12.3.1 / After Effects 22.4.0

Make sure in the Output Module settings that when choosing Apple ProRes 4444 the Pixel Aspect Ratio is square (1.0) and not rectangular (custom). Also, make sure the Resize checkbox is unchecked.
