I attempted to enable a new 3rd party mod after having downloaded latest update to dev-branch. The game started as normal. Upon reaching the main menu, I attempted to access the "configure addons" function but game froze, requiring Task Manager to force quit the game.
Attempted several times with no other applications running. Still froze.
Deleted all mods from Arma 3 folder and reverted Arma 3 to vanilla status. Attempted several times to access "configure addons" but game froze every time.
