Multiply render errors in MediaEncoder

With the new PrPro & MediaEncoder (v22.5) I encounter numerous flaws. Firstly, I need to be lucky to transfer multiple selected sequences from PrPro to MediaEncoder anyway, because most of the time clicking on "Send to Media Encoder" results in ... nothing at all. And secondly I very often get errors in trying to render the sequences in MedieaEncoder whereas I can render them without problems directly out of PrPro. The only thing is, there are mostly 15-40 sequences and it'd cost so much time to render them individually. So this is why ME is there, isn't it!?

Most common errors I came across so far:

• Error retrieving frame
• A low-level exception occured in : Warp Stabilizier
• Frame substitution recursion attempt aborting after multiple attempts on file

I'm working mostly with DNxHR SQ footage and rendering also into DNxHR SQ or h264/h265.

I'd appreciate any suggestion for solving this behavior.
