Help, support CPM build

Just want to let you know that I’m getting black screen in CPM A10 and A11 for a particular multiplexed file I made. I do not get black screen with A09 or the latest nightly. The file is Akira multiplexed with 4 video streams (Dynit 2019 HD, Crunchyroll 2022 4k, Funimation 2013 HD, Bandai 2009 HD), and a few audio (2009 Hypermix, 1988 2.0 Dolby surround, etc).

I’m not sure if it is at all related, but black screen appears to be a skin issue for some users and was recently fixed for them: Learning about Dolby Vision and CoreELEC development - #606 by doppingkoala

For now, I’m using the latest nighty or A09, depending on my needs. Sadly I cannot use A10 or A11.

I’d be happy to help diagnose the issue but would need guidance on how.
Thank you.
