Merged AOVs in RenderOutputDefine keeps failing on ktoa

Hello everyone,

Everytime I try to disk render my scene with ktoa, the renders fail on the last RenderOutputDefine which is the merge one. I already checked the "How to create multichannel output in KtoA?" topic but it wasn't helping.

The error is:

Running command: 'C:\Program Files\Katana4.0v5\bin\ExrCombine' 'C:/Users/Utilisateur/images/TEST/specular_0100.exr' specular 'C:/Users/Utilisateur/images/TEST/diffuse_0100.exr' diffuse 'C:/Users/Utilisateur/images/TEST/merge_0100.exr'
Render stopped with exit code: -1073740940
CommandLineRender Error: Render stopped with exit code: -1073740940

Render error. Time elapsed: 19.51 s

Node 'Render1': Render1 failed with a rendering error: Render stopped with exit code: -1073740940

All my file extensions are exr, all the types are raw and I unchecked the tiled option for every ArnoldOuputChannelDefine.

Is that connected to the fact that after every output there's the name like specular, but after the merge one there isn't anything?

I do apologize if the issue has already been resolved but I couldn't find any answer.

Thanks in advance!

ExrCombine is a post-render process. The Arnold render itself finished successfully, it's the the Katana utility ExrCombine that fails.
Perhaps it is this?
