Crashes Trying to Make Videos

Ever since the new launcher, I can't make videos of Minecraft.

• Load into Minecraft flawlessly
• Play Minecraft flawlessly
• Open video software flawlessly (Open Broadcaster Software)
• Press "Record Video", Minecraft crashes

I have many Minecraft videos already, of 1.10, 1.11, and 1.11.2; and I know it's not my computer causing the crash. It has only started occurring since the most recent launcher update.
