The issue comes from a recent update of AMD Gaming Evolved.
When using this program it can cause other programs working with Java (such as WAKFU and other games), to stop functioning and encounter this error.
We are looking into a solution even if this is a bug not directly linked to WAKFU and present between Java and AMD.
Until a solution is found, you can deactivate AMD Gaming Evolved in order to be able to play WAKFU again when encountering this issue. To do so, please go to the program’s preferences by right clicking the icon next to the time on your desktop, and modify the preferences in order to deactivate it. It is also possible to select to no longer launch the program when starting Windows.
