Driver stuck on "Enabling vibration..."

[bladeSk]

I managed to pair the JoyCons successfully, they show up everywhere in Windows, however, when starting the JoyCon driver, it gets stuck on the first JoyCon that was paired. The blinking lights animation on the JoyCon slows down and Driver's window stops responding. This is the log output:

Sometimes it gets stuck on the first "Enabling vibration..." message. I'm on Windows 8.1 x64 with latest updates.

I meet the same error in USB connect mode.But in wireless/Bluetooth mode it works without this question.
