Had the same problem on Mojave. On Catalina however it works just fine.

Thanks for reporting. Maybe bluetooth is disabled within your bios?

Apparently it's having an issue when using with itwlm: OpenIntelWireless/IntelBluetoothFirmware#177

I'm going to remove it.

This is an upstream bug.

Even without the itwlm, the IntelBluetoothFirmware is constantly trying to upload the firmware, and it will fail and stuck at a particular loop procedure and will time out eventually and continue to boot. Note that this loop procedure is still going on after the OS boot on, you can still find it in Console.app by looking at kernel log.
