Crashing game

I have played this server for a long time and I have never brought problems, but lately I crashed the game in dungeons or using tickets or anywhere and it is annoying at the time of the farm, I have lost coins and time for farm , I do not know if it is a failed patch or something, I have uninstalled and reinstalled and downloaded but the problem persists, I would like some help with some file or something appreciated please. Thanks in advance.
