Since 2.9 hit I have been unable to join certain MP servers; particularly those running large missions with many AI units. DCS will connect to the server, finish loading the mission and then as soon as role selection comes up completely freeze. When clicking the mouse it shows the prompt that the application is not responding; I have waited for >15mins and it never finishes so the only option is to kill DCS via Task Manager. This happens in both ST and MT versions, with VR and without. Servers with smaller missions (few or no AI units) load just fine and allow me to play with no issues.
To troubleshoot I have cleared all mods, ran a full repair via Steam, used low settings, deleted the "Saved Games\DCS" folder and even installed a completely fresh standalone open beta; none made any difference. On the Windows side I have installed all Windows updates, run DDU (in safe mode), installed the latest nVidia drivers (546.65), cleared temp folders, killed all background applications, manually set affinity, enlarged the page file; again to no avail.
I have no issues running any other heavy applications/games on my system and am running out of ideas besides reinstalling my OS, which is something I'd rather not resort to atm. Any help resolving this would be greatly appreciated.
My system specs:
AMD Ryzen 5800X3D, 64GB DDR4-3600, RTX 3090, 2TB Samsung 980 Pro NVME SSD, Windows 10
