game crashing nonstop, almost always crash after minimize

i use trade site so i must constantly minimize the game. it's extremely likely to crash after i return, and if it doesnt crash the graphics are gone and everything is grey. the crashes and grey graphics tend to happen if i minimize during load screen.

also often i cannot see other people's invite and trade requests at bottom right corner, i must go into social to see it, and other player's names are often blank.

when it crashes it says "deadlock detected"

same here I cant minimize the game - it crashes.
But yesterday I could play good had only one deadlock (after minimizing and trade)
