Lots of bugs, please help

So i have many kind of bugs, but now first of all, i can’t even log in. at very first there came ingame a bug saying “Serialization error, corrupt data found, please verify your installation” i did verify and it didnt still work. Then came some other bug but i dont recall what was it like. Now i cant just log in because it says “You do not have any debugging symbols required to display the callstack for this crash.”
