Remove door and open up

Either you replace the A studs with C 24 studs, or you screw the B studs into the A studs. All according to the attached image.

It's not so easy!!
Since we don't know anything about the loads, it's impossible to calculate it. It's often the buckling length that is critical in these cases. Additionally, the deflection on the beam increases with longer distances between the pillars, so it may need to be replaced.
Everything built in there is dimensioned to handle it as it is now, and if you start changing something, you have to recalculate everything again.

Read my previous post. It is possible to calculate the loads using the floor plans. My estimate shows that the short span means that the beam dimension is sufficient. The problem is the studs of unknown class, which with a depth of 70 mm, limit the buckling load.

Received drawings (everything they had, 4 in total) from the City Planning Office.

Any further thoughts on how to proceed based on the documents I attached?

The studs in the load-bearing main wall on the ground floor according to the technical description are 34x70 c/c 300 mm. Do the studs around the door opening have that dimension?

The studs in the load-bearing inner wall on the ground floor are, according to the technical description, 34x70 c/c 300 mm. Do the studs around the door opening have that dimension?

No, all are 45x70.

Then it applies as I wrote earlier.
