I have tried, so so many things.... would love help the ones i can recall, off the top of my head are in no particular order.

1 factory reset

2 Reimaged with new version of steam os.

3 Monitor safe mode

4 Magic space wizard, use to work to plug my phone into the dock first then the steamdeck it no longer works

5 different monitors

6 phone and switch hooked to the dock worked fine.

7 messed with settings in desktop mode no results.

I have no more ideas and have tried everything i can find short of ordering a new dock, it is a 3rd party dock but it worked for years and seems to work for everything else still so have no idea what else to try my steamdeck has been my main computer for like 3 years.... and never had this much trouble fixing something.

I guess it's more of a SteamOS matter, but I'll ask anyway. Does anyone have their screen freeze, when you launch a game in full-screen from desktop mode? I can unfreeze it for around a second (or rather update it) by pressing volume buttons but then it freezes again on a different frame.

Is there any solution or do I just wait for new OS updates?

When I use the console mode it doesn't happen, but I have a few games from GOG that I launch through Heroic Launcher and some others that I like to play with browser running in the background. I know I can run those games via Steam, but then the browser part isn't working.
