Hello everyone.
How should the studs be arranged? From the outside, I have horizontal 45*45, vertical 145*45. Then it should be 45*45 again, but should they be vertical or horizontal? Does it matter? On these, there will be particle boards and then gypsum.

Nail them standing on your 145s, so you can mount your boards vertically and get the joints on the studs. I guess the idea behind the construction is that the plastic should be attached between the 145-insulation and the inner 45-insulation to facilitate electrical wiring?
I hold the opposite opinion. Mount the 45s horizontally to further break the thermal bridges. Then you mount the chipboard or alternatively OSB horizontally on top of these. The drywall can then be mounted vertically or horizontally; it doesn't matter because you attach the drywall to the chipboard.
I agree with ACME that the plastic should/ought to lie between the inner 45s and the 145s.

At my place, electrical wiring was done before I applied the plastic covering.
No risk of condensation forming between the insulation then?
Found this, so both options work
Repositioning of the vapor barrier in the construction
It is advantageous to move the vapor barrier, for example, 45 mm from the interior of the construction. This provides better space for routing electrical conduits and avoids puncturing the vapor barrier. If there are leaks in the vapor barrier, convection can occur, transporting warm moist air into the construction, which can cool down with the risk of condensation. At an air temperature of 20 °C and a relative humidity (RH) of 50%, the insulation outside the vapor barrier should be at least twice as thick as inside. At lower air temperature or higher relative humidity, the placement of the vapor barrier should always be calculated before any repositioning.

If you nail the 45x45s lying outside the plastic, the installation work becomes even easier/faster, as you avoid drilling any holes in the studs. Additionally, the thermal bridges are reduced, as already mentioned.
You are naturally right. Lying down is reasonably better in terms of thermal bridges, although I don't know if it makes much difference with a 45:an really?
But you can reroute the electrical conduits unusually easily if you cross-brace on the inside of the moisture barrier? Horizontal conduits are just laid out, while vertical ones are placed between 45x45 and the plastic.
When you reach the outer wall corners, it gets tricky. To attach the panels, you place vertical studs there, and then the electrical conduits can't get past the corner. But then I read in a thread here, a year ago or so, about the tip to not place these vertical studs but rather screw the corner together using metal brackets (on the backside) instead.
A "problem" with horizontal studs can be that due to the current ceiling height, you might end up with a very unfortunate cut of your particle boards, which might fit better standing instead.
But what do you say about horizontal studs, standing particle boards and plasterboards? No blocking at the edges of the particle boards but instead staggered seams. The boards hold each other's seams together, so to speak.

I was thinking for a while about how to place the OSB boards until I decided to use raw planks instead (end-matched), so the job won't be too heavy either...
