Urgent! My game character needs help！

Dear GGG administrator, hello！
My question is：
My game character crashed after activating the demon skill,
and the demon skill still appears on the selection page of the game character.
Once I select the character and enter the game, it crashes and crashes.

Please investigate and assist me in resolving this issue as soon as possible,
and also report the problem to the game engineer and fix it as soon as possible,
as there are still a large number of game players like me who have similar issues that have not been resolved.
Thank you very much!！！
