Problem with 10.5.x transcoding

Hello, i use jellyfin in docker on Synology (xpenology). I’m stay with 10.4.2 for Now. I’ve tried a 10.5.0 and then 10.5.2, for both i found a problem, for me.
With same config used before when play a video that transcode, at any resolution, i reached an error that there is missing profile.
I try some change on the config but without result. Only if disable a hardware transcode and demand on cpu the worload, all work fine.
I miss something?
