Breaking: I found a way to solve the problem
It can probably be done smarter, but the way it was solved was to delete (or rename) the Packages folder, MSFS will rebuild it after a restart, copy Bsq King Air and Asobo King Air from MSFS2020 to the Community folder and restart the sim.
I am soooo happy, because now I can run the Gps via Glassout.
And it turned out that I was not the only one with this problem, my brother in law had the same problem.
But @Black-Square : pretty pretty please with sugar on the top: please release a 2024 version. I got cat pictures
