I am new to Intiface and pairing toys to in general let alone my pc. Intiface crashes and freezes on me during engine start. I cannot view apps logs to see error code unfortunately. Repeater mode does not crash. I haven’t even connected any toys to it yet 
complete pc noob so any help would be appreciated.
We’re going to need to see your logs (there’s an option to send them to the developers in the settings tab).
It’d be a good idea if you could describe what you’ve done so far though. You describe pairing devices with your PC, but that shouldn’t be needed: Intiface will scan and connect for you.
Which toys are you trying to connect?
