ᐅ Removing a Wall in the Basement / Load-Bearing?

Hello everyone,
the following wall is not shown in the floor plan (basement). Can it be removed, or is it load-bearing?

Based on the pictures? They can be ignored or not. For an assessment (which is just a gut feeling anyway), these close-up shots are unfortunately useless. Do you have the floor plan (basement and ground floor)?

The wall is not present in the basement. Unfortunately, the plans (for whatever reason) do not match reality. I have redrawn it.
Basement

Ground floor

Are these really stacked floors of the same house? When I go upstairs from the basement, the staircase in the kitchen on the ground floor is missing.

Yes, they are. Unfortunately, they are mirrored for an unclear reason. The original plans are unfortunately a mess.

Tip – non-load-bearing. But whether it provides bracing, because the adjacent wall was removed (that’s how I interpret the wavy lines), no one can say. Maybe it was once a requirement in order to remove the other wall.

Only the structural engineer will be able to give a final statement. Sorry.
