GEPRC Span Tower F405 gets very hot!

Hello everyone!

So I got a GEPRC span tower F405 Flight controller. and the VTX/flight controller board gets very hot when i power i via USB, and betaflight controller can´t connect to it anymore. my guess is that the VTX/flight controller board is fried, but i want a second opinion from you guys? I have attached a photo of the part that gets very hot.
