Cannot reactivate Bluetooth at all, have tried everything I can think of or find
I've got an ASUS Vivobook Pro 16x from I think 2023, running Windows 11 Pro.
Earlier today I went away for a few minutes, and I think it went to sleep, and when I came back the Bluetooth no longer worked. It completely disappeared from the Quick Tray and I couldn't find any way to reactivate it. I looked up a ton of suggestions for support, and either they didn't work or were impossible. i.e.: "Go to Device Manager and go to Power Management settings for your Bluetooth adapter." (There was no Power Management option.) "Go to Services and restart Bluetooth Support Services." (Windows failed to stop the service, so it couldn't restart.)
The only thing that worked, by accident, was when I went into Device Manager and picked "Check for Hardware Changes" on my Bluetooth devices, and that crashed my computer. But when it restarted, Bluetooth worked again.
Unfortunately, the computer went to sleep again later and the same thing happened. I was not able to recreate the solution. I tried cold rebooting and that didn't work either. I even got in touch with Microsoft help and they couldn't help me.
Eventually, I found an updated Bluetooth driver on ASUS' website, and installed it. But when I restarted my computer... Bluetooth disappeared entirely from my Device Manager! I did find a USB device that failed to identify, and when I uninstalled it and checked again for hardware changes, Bluetooth returned. But... the driver listed for my adapter seems to be the same one as before I installed the update. And... I still can't get any of it to reactivate.
I have no idea what to do here. Everything I've been suggested is either impossible or doesn't work. Everything I've tried doesn't work. I cannot figure out how to reactivate my Bluetooth adapter. What am I supposed to do? I use a Bluetooth wireless mouse, so this is a huge pain for just my everyday usage of the computer.
