Why has my Wireless AC 9560 Bluetooth range suddenly dropped to 1 foot?

[SPedi]

I've been using bluetooth devices on my new laptop for several weeks without any issues until the last few days. I'm still able to pair/unpair Bluetooth devices with zero issues but the bluetooth range is extremely poor. After ~2 feet, the signal starts to stutter/drop on my headphones, and even the slightest amount of physical interference such as my body seems to cause crackling.

I have tried to reduce potential interference by powering off my wireless modem/router, moving my laptop to an isolated wooden table with no peripherals connected to it, and then tried multiple bluetooth headphones all with the same result. The bluetooth signal seems to only reach about 2-3 feet from the laptop and even turning slightly causes the headphones to pop/crackle badly.

This is driving me insane.

1. In your Intel Wireless-AC 9560 adapter you have two radios: the first working at 5GHZ and the other is serving Bluetooth and 2.4GHz WiFi.
2. Is your WiFi 2.4GHz working good?
