After Effects 2022 versions 22.1.1 through 22.3.0 will not open large PNG files (8960x1760) saved out of photoshop. The following error is on project open "AEGP Plugin PNGIO Support: PNGIO library error: iTXt: chunk data is too large ( 5027 :: 12 )". Opening in AE 22.0.1 is fine.
Same issue, it's not fixed since 22.1. Both MacOS and Windows will have the issue. I have to export the png files from photoshop again to get it properly loaded in After Effects. Please fix it.
