A lot of people using Win10 have this problem. Sometimes it is caused by auto screenshots (you got an achievement, killed the boss, made a level etc) and suddenly you your client stop working. Sometimes a simple movement, map click makes it stop working as well, suddenly on the bottom of you your game window a small sentence in red appears and says that Client could not load an image... or "bad_module_info" stoped stopped working - this error window often appears and suddenly you client is shutting down.
To sum up - this is kind of graphics problem.
I have no idea how to solve it, the problem must be in client. I know people to tried guides found via google about "bad module info" error and it helped. On the other hand I tried everything and nothing has changed. I even did a full comp format and nothing.
My suggestion is to disable possibility to make auto screenshots by client.
