Application locks up on Windows; dev console does not return anything



I’m writing an Electron application (GitHub) and have hit a bit of a snag. Whenever I press “Scan”, my application locks up. This only occurs on Windows. Additionally, as pictured below, the dev console allows me to type but it does not return anything, nor does it show any errors. The actual window cannot have any text selected and is essentially frozen.

Visual Studio shows three threads exiting with 0x0, which should be normal?

I have no idea what’s happening, so any help would be appreciated.
