Details:
Screen name: com.brandon3055.draconicevolution.client.gui.GuiFusionCraftingCore
Mouse location: Scaled: (357, 198). Absolute: (1071, 483)
Screen size: Scaled: (640, 360). Absolute: (1920, 1080). Scale factor of 3

Will be fixed in the next update. In the mean time don't press shift while you have that gui open. The crash is caused by addition information that is displayed while holding shift (mainly just the craft progress gets a couple decimal points) I suspect there is a moment just as the crafting begins where the gui recipe state is invalid. Holding shift at this time will cause you to crash.
