Advice for new camera

Hi guys I’m new to this forum and having a question about my new camera. I’m a potrait photographer mostly for wedding and model photo shoot.

I had a Nikon D750 and 85mm 1.4 nikon lens. But my whole backpack was stolen few months back when i’m going on a vacation. Leaving that heart broken story apart, I want to buy new stuffs.

Can you please suggest some camera with the D750 price range or little bit higher? I’m okay to move Sony or Canon or Nikon. Also lenses similar to nikon 85mm 1.4.

Thanks.
