A little bit ago, bluetooth stopped appearing as an option to use. I cannot turn it on or off as there is no option. I've tried troubleshooters, checking for windows updates, and turning it on and off. Looked through Device Manager and tried re-installing latest Win11 drivers from the Intel official website. Went into Reliability Monitor and am pretty soundly stumped, and out of my depth at this point. I may be going to bed soon, so I may not respond quickly. Please help.

Hi, thank you for replying, in that case, I suggest doing a system restore wherein it will restore the PC, where it was working properly, to do that, kindly follow the steps below:
Press the Windows key + R, then type in:
rstrui
Then hit OK.
Follow the prompts and select the time and date when the PC is working fine.
Follow the prompts again until it restores.
Thank you very much! This worked like a charm. Have a wonderful day!
You are always welcome, and I'm glad it is now all good.
Hi, I'm Bernard. I'm happy to help!
The logs you have provided show a Blue Screen error, which points to a hardware-related issue based on the description. May I know when the issue started and whether it worked fine before?
While waiting, I recommend rolling back the Bluetooth driver by following the steps below:
-Press the Windows key + X
-Go to Device Manager
-Expand Bluetooth
-Look for a Bluetooth device or a similar name
-Right-click and click Update Driver
-Select Browse my computer for drivers
-Click Let me pick from a list of available drivers on my computer
-Choose an old driver or another driver name, then select it and hit Next until it installs.
-Restart the PC and check.
Note: If the issue persists, please download and install a Bluetooth driver from your manufacturer's website.
It started at 9:19PM today, and was working entirely fine for years prior. I've already deleted and re-installed up to date drivers from the ASUS website (laptop is an ASUS Viviobook). However, this did not work. Furthermore, after deleting and reinstalling the "bluetooth" section that was previously in the Device Manager (under show hidden) is no longer there, even when scanning for hardware changes.
