Encoding error with Media Encoder vs PP encoding

I'm having a strange issue whcih is new on a project. When rendering in PP, everything is fine, when rendering in ME, the gamma and colour of one cameras clips is wrong and also an overlay that is hiding some cropping of the frame is not being rendered. This is a project that I have been working on for a few months and everyhting was fine until the latest update. The error occurs on both Windows 11 (latest) and Mac Sequoia 15.2. Both PP and ME versions are the latest. I would upload frame grabs of the issue, but the forum is not allowing me to upload jpegs for some reason. I've attempted to attach them.
