Load-bearing "beam"?

[Manhood]

Renovating my newly purchased 1.5-story house and I see a previous renovation where a load-bearing wall on the ground floor has been opened.
The "hole" in the wall is directly under the upstairs wall.

The opening is 2.2 m wide and there is no glulam beam, just an upright 45 x 200 mm stud with an additional 25 mm screwed on the side.

Is this sufficient to support the wall, or is there a significant risk that something will happen?

Hello!

From what I understand, you probably need to apply for a building permit for similar interventions.
So maybe you can find out something that way, if it has been applied for?

25mm what screwed on the side??

It might be that you need planning permission if you significantly change the building's function, as it is nicely put.
