Type of Bug: in-game
Details: It seems that when Jhin casts his W in the FoW and hits an Enemy with it, it can lead to freezes for the opposing team.
Another Video in which the bug can be seen: https://youtu.be/lIYCMxnwaqg
In both instances the jhin had Aery as keystone, hit an Enemy with W and was in FoW.
The Skin does not seem to influence it, because in my game he had the Bloodmoon skin, while in the other video he had the SKT T1 Skin.
I have not tried to reproduce the bug.
