Infernalist Hexblast Portal Crash

I came across a bug, where my crashes every time I cast Hexblast and click on the "Create Portal" button, during the animation of hexblast. This happens only while in demon form and should be reproducable. I just did it in a map 5 times in a row.

I happened upon it, because I have Hexblast on my left mouse button and I sometimes miss the portal button, which leads the cast, the second click and the crash.

I can confirm with Eye of Winter. If I miss the portal button, Eye of Winter casts, and if I click the portal button right away the game crashes. Also while in Demon Form.

Can confirm, game consistently crashing when opening a portal in demon form during hexblast/spell animations.
