Hi,
I am not a builder, but I am fairly sure the answer to that question is no.

My housing association appears to think it will resolve the problem, but I have lived in this property for ten years, and there has been a long-standing damp issue in my bedroom. The problem is in the dry-lined wall with the window. Whenever it rains heavily, I can hear dripping inside the wall. It sounds as though water is dripping onto something inside the wall, possibly timber beams or a flue pipe. In the past, the wall has become wet during heavy rain, and on one occasion I could actually see water running down it.

In 2022, I also had a leak from the flat above after a boiler was fitted. Water came through my bedroom ceiling and down the walls. I was left with water coming in for several days before it was properly dealt with. By that point, mould and even mushroom-like growth had started coming through the walls. Just this year they came to fix it. They lied to me and even moved me out for 2 weeks* because the "walls needed to be taken down". I got home 3 months later due to "invoice squatting" to find they have put thermal boarding over it. The wall they did smash down, I believe, contained asbestos, as the ceiling tested positive for chrysotile and left my flat covered in dust. With that amount of damage and exposure to moisture, was this the correct choice to make by covering it over with thermal boarding? I think those walls needed to be taken down and the cavity inspected at bare minimum. It would be good to hear what you think.

Also not sure if the drip would do this, but the area where the drip is, the plinth on the external side was also damaged and needed repairing, it's in the photo below.

I'd suggest that someone needs to take the plasterboard off and see what's actually happening rather than trying to guess at solutions while blindfolded.

At the very least, that boxed in corner in your second-to-last photo needs opening up.

Contact your council if they're not forthcoming with solutions. They're legally required to ensure your home is habitable and safe.
