From one day to the other, my client has begun crashing upon logging in. The moment I press the 'Login' button or hit Enter on my keyboard, the program crashes, and I'm met with the error message "An error has occurred in World of Warcraft". The error report states the following:

Exception: EXC_BAD_ACCESS
Error Code: 0x85100086
Time: 2017-04-23 17.59.34 CEST

Error: EXC_BAD_ACCESS KERN_PROTECTION_FAILURE 0x30d11eca

I have tried deleting the folders WTF, Interface, Cache, Updateswith no succes. After that, I tried re-installing the game, which didn't work either.

Can someone help me with this issue?
