What does the crash say? What error?

thats the probleme no error at all just the game is not responding and i have relaunch it again and if i am inside the instance there is a chance that it will crash again
i didnt add any new addons at all nor my old addons cause this like there is nothing between after and before the crash i redownloaded the whole client and did the LAA programm thing
