Multichannel EXR's with redshift and maya 2022

When I send a Maya 2022 Redshift scene on Deadline (10.1.18.4) (Maya batch + Redshift job), it’s impossible to render multichannel exr’s, only the rgb is contained in the file, while everything is fine if I send a normal Maya Batch render. Cryptomattes are not rendered neither on deadline.

I have been able to have better success by configuring deadline in the section “configure Plugins/Maya Batch” and putting the option “Use Python 2 (Not Mac OS)” at True. This option finally allows to output multichannel exr’s and cryptomatte, but for some reason it does not work for the first frame of the task - the first frame doesn’t have cryptomatte and aov’s.

Can anybody here help? Thanks
