Windows 10: Logitech MX Master mouse driver error Windows 10 Pro 1909

Hi,
I had recently changed my wireless network card in my laptop from Intel AC 3160 to Intel 7260 but my laptop did not support that 7260 card so i put back my original network card. Both wifi and Bluetooth were working fine before. After i put the card back, wifi is working fine but Bluetooth is having problem with my specific device MX master mouse.

Bluetooth works fine with my Bluetooth keyboard and Bluetooth headset but whenever i connect my mouse, it connects and then it shows driver error.

I thought it might be the mouse, so i connected the mouse to my second laptop and it successfully connects to my second laptop and even my phone perfectly.

So the issue is quite strange. The mouse connects fine to other device but has error with my laptop. The laptop connects fine with other bluetooth device but gets driver error with the mouse.
I checked device manager and there is Bluetooth Low Energy GATT compliant HID device. Tried updating that device but it shows best driver is already installed.

I have tried reinstalling the bluetooth driver from dell as well as from Intel but the issue still persists.
I have tried installing logitech options and logitech setpoint but that didn't help. Issue still persists.
No option to rollback driver either, its greyed out. I guess i must have uninstalled the previous version of driver.
I don't have the unifying receiver so without bluetooth, cannot use it on this laptop.
I have made sure the mouse is on right channel
I have tried removing and re adding the mouse. it reconnects but shows the same driver error

I am trying to install a Logitech MX Master 2s mouse. The mouse is on but Windows cannot detect the new device, the screen shows it is searching, but remains blank. Also Bluetooth is confirmed on.

 

Logitech MX Master Mouse utility won't launch after Creator's Update

I have an issue with my mouse's utility software. It's a Logitech MX Master. The file in question is "logioptions.exe". It won't open. I'm currently running W10 build 15063.138.

Prior to the Creator's Update, the utility worked just fine. Since then, it fails to launch. I put the question to Logitech's own support forum and haven't received a response yet.

So far, I've tried uninstalling and reinstalling the software. I ran Windows compatibility troubleshooter, which did nothing. I can use the mouse but I can no longer configure any of the buttons.

Any takers?

 

Need Mouse Recommendations

Basically, what is the major difference between the Master and Master 2S?

Great suggestions!
