ᐅ Fill vertical 7 cm thick and 20 cm deep slot in load-bearing wall.

Hello experts,
I am currently facing a challenge and think this is a question for the masons in this forum.
I had to replace the electrical wiring in a two-family house. After careful analysis, it became clear that the 4-core 10mm² (10.7 AWG) cable also needed to be replaced with a 5-core 10mm² (10.7 AWG) cable. So, the cable was replaced from the basement up to the first floor. For this, the walls had to be channeled open with a slot about 7cm (3 inches) wide and 2.75m (9 feet) high. In the 1970s, the cable was simply embedded directly in the wall during construction. Now I have two fairly large slots in load-bearing walls in two apartments that obviously need to be repaired.
This is where I need advice from the experts among you.
How can I restore the maximum stability of these walls?
Have the slots significantly weakened the walls, considering they are vertical?
There are also quite a few cables inside the wall now: two main cables plus six NYM 2.5mm² (≈14 AWG) cables. Will they cause any problems when closing the slots?
As a “layperson,” I would have simply filled the slot gradually from bottom to top with expanding mortar, to apply some pressure on the whole structure. Or is that rather counterproductive?
I would appreciate some digital support from you.
Thanks in advance and best regards,
Sebastian

Uh, no, behind. If I understand correctly, you chased a cable out from the opposite side of the wall. With such a haphazard approach, I probably don’t need to suggest that you illustrate your thread with floor plans. But maybe with photos?When chasing out the cable, I of course worked on the side where the electrical panel is located. The assumption was that the cable also runs inside on that side. Actually, it ran diagonally inside the wall. I’ve attached some photos. The same applies to another floor.

Why didn’t you just cut new channels, and not so deep!! Personally, I would have left the old cables in! Now the damage is done.Because I thought the cables were at the front. Once I started, I wanted to get it done. Yes, it would have been wiser to leave them in afterward.

Hands folded and off to the structural engineer I spoke with a bricklayer. He said it might be possible to rebuild it neatly using expansive mortar and by removing the bricks. I would like to put this up for discussion.

There is a good reason why structural engineers need to study.

The third picture in particular looks like you tried to perforate the house crosswise with an angle grinder :-(
Why not just open one surprise first?
Are you a humanities scholar, or where does this already remarkable lack of knowledge about building anatomy come from?
Be sure to make videos of your work—you’ll become a click billionaire within a few days, if not crash the entire internet. That would surpass every cycling cat singing baby.
