These are also available with shorter "wings", or you can grind off 1.5mm from each wing if it becomes too "deep". There is another variant with a full "wing" that requires less space. It can handle essentially the same load. Search for toggle or toggler on Google to see.
Check out customer comments under the "Technical dokuments" tab a bit further down the page I linked to. It is loved by, among others, TV/AV installers.

Hi, I looked up these Snap Toggles as I haven't used them before. According to the information I found, they unfortunately require 48mm of free space behind the panel. That's still 3 mm too much

I mounted a large TV as I described above, with a wooden board. However, I only had steel studs behind and had nothing to attach to them. Used snap toggles to attach the wooden board. It was indeed double plasterboard. But it held well. Should be noted that the TV didn't have as large of a retractable arm as yours. But it's undeniably good stuff.
Snap Toggle M6 plasterboard anchors support 100kg each in single plasterboard. No problem holding your TV. I have tested it myself. Also mounted overhead cabinets in the laundry room with 2 Snap Toggles per cabinet in single plasterboard. Tested by hanging on the fixture (over 100kg) without any problem.

Available in well-stocked hardware stores.
Sure these work well, perhaps even perfectly if you hang the TV directly against the wall, but now it's a mount that allows the TV to swing out from the wall, and then it's not only vertical forces on the fixture but also tensile forces. This fixture might hold for that as well, but I wouldn't have tried without placing a board between the studs to then attach the bracket to the board. It's the easiest but perhaps not the prettiest. For it is a recessed board behind the plasterboard, but this solution clearly requires more work as you have to cut or tear down the plasterboard to fit the recessed board or nogging.
It works, but a board behind or a nogging allows you to use regular wood screws. Easier to restore since the holes are smaller. Toggle requires a slightly larger diameter on the holes.

As long as the screws hold in the board, it should be fine. Uncertain about the definition of glue board?
Screw plus molly: the screws in the stud won't come loose if you put it that way, the question is rather whether the plasterboard gets damaged over time. An alternative is to center the board over a stud with 2-3 screws if you really want to keep the size down.
I write too fast, meant glued laminated/glue joint board, e.g., pine or oak.
Many good inputs and suggestions but unfortunately not getting any wiser.
Sawing or cutting open the wall in the middle of the Christmas season doesn't seem like an option.
These are what I'm considering now.
Option 1:
Screw external plywood onto the studs.
This one: [link]
What is the most suitable screw to use when attaching the TV mount to the plywood?
Or attach the TV mount only to the stud on one side and Molly on the other side.
Keep in mind that you have center-to-center measurements of 60cm. So with a 600mm long sheet, you only have studs for the last 2cm on that sheet to screw into; it should ideally be a bit longer than 600mm but it will work.
The right screw should be a so-called mounting screw. Essve's range is always good.
What do you mean by "expanderbult" M6? Is it like a "Molly" bolt or equivalent?
The mentioned bracket must be attached to the wall studs to remain secure. If the bracket's holes don't fit, you'll first need to attach a plywood board or similar to the wall studs, which you then screw the bracket onto.
At first, I was a bit surprised that you don't even know or could guess or Google what an expanderbult is.
But then you had a good idea about a board that should be attached to the studs.
