Static question: Is this wall load-bearing?

Hello everyone,

I have now spoken with several people. We are quite sure that the following wall (marking) is not load-bearing, but we are not experts. Maybe there is someone among you who can say with 100% certainty whether I can remove the wall or not.

The wall is made of alluvial stones.

You can see everything else in the photos! I look forward to any help ;)

How thick is the wall, without plaster?

Only the structural engineer can say that with 100%, but I would say: yes. I am glad that apparently there is still a considerate rethinking about refraining from the wasteful demolition of the existing building. But I still find it unwise that you are getting distracted by a handful of threads about this project instead of returning to and continuing the thread there. Only a few fellow discussants have an 11ant memory and/or take the trouble to collect and recap your scattered information.
