[SOLVED]
In my case, somehow it is resolved by switching primary and secondary weapon, vice versa, before casting her 2nd, after that, I can cast wisp's 2nd ability without having the freeze anymore, I do this every time I start a mission. However, if I don't switch weapon at first, the freeze will remain. So I don't know, I somehow found a way to "fix" it just temporarily.
What I don't understand, this "freeze" only occurs in Wisp's 2nd, I tried all the skill from every frame I have, there is no freeze. This thing had never happened before this Dante update. Good thing I somehow found a way to make it disappear temporarily.
