Issue: How to fix btmshellex.dll error on Windows?

Hello, all. After Fall Creators Update, I cannot connect any Bluetooth device to my PC. I’ve checked that the status of the Bluetooth adapter driver reports an error, which says: “This device cannot start. (Code 10) STATUS_DEVICE_POWER_FAILURE.”

I tried updating and uninstalling it, but after that I started getting a message “There was a problem starting C:\\Program Files (x86)\\Intel\\Bluetooth\\btmshellex.dll. The specified module could not be found” on start up. Please tell me what should I do?
