There are 2 issues - you are writing output image with node to same location as render, but ths is not causing problems. The problem is caused by glare node with combination of PNG output format. Glare node causes image to have pure emissive colors which are not supported by PNG. You should use format like OpenEXR.

Alternatively you can mask this area and override alpha yourself, or apply greenscreen to convert pure emissive colors to normal transparency.

Richard Antalik (ISS) closed this task as a duplicate of T81199: Some effects [bloom, smoke, fire, ..] still don't save in PNG with transparent background (occlusion vs. emission).Sep 29 2021, 6:34 PM
