I have a load-bearing wall consisting of 75*75 mm studs and approximately 1 cm thick raw wood on each side. Perpendicular to this wall is a non-load-bearing wall. In the non-load-bearing wall, I want to build in a sliding door. To fit it in the open position, I need to let it go into the load-bearing wall. So, I want to cut a slot (about 10 cm) in the raw wood on one side of the load-bearing wall. Will this affect the wall's load-bearing capacity?

The raw plank affects more how steady the wall feels but hardly the load-bearing capacity in any significant way. That is such a small intervention that you can go ahead with what you have planned.
 
There should be no problem at all. Good luck with the construction.
 
As mentioned above, the load-bearing capacity is probably not an issue but there is a lack of support for the råspont in both the load-bearing and especially in the non-load-bearing wall. If you can place a new "gul" stud on each side of the slit and screw, for example, a plyfa strip on that stud that then extends into the non-load-bearing wall where you attach the råspont, you will regain some stability.
