No Units (Mount Blade 2: Bannerlord)

I created an army, when I try to attack, it doesn’t work, the Done button does not work, but when I attack without an army, everything is fine, the Done button works / what could be and how to solve this problem? I simply can’t start a battle and get out of it, and this is only when I gathered an army / but I can’t understand the reason at all ....
