intermittent Problems with Touchpad and Mouse buttons

Hello all.
I have a Dell XPS 15 and use a Bluetooth keyboard and mouse.

I have not had any issues until yesterday. I'm not sure when the last win update occurred

Problem:
- On Startup sometimes there us no function of keypad pr mouse buttons. However, the keyboard controls/shortcuts still work and I can move the cursor around the screen either on touchpad or mouse. After approx 5 minutes, this issue will disappear altogether and I get full functionality. However, again after approx 5 mins the problem will resurface.

- This is an intermittent problem. I may be working for ten minutes and suddenly my buttons on touchpad and mouse will not click on folders/images, etc to open. Also when I go to open a new browser tab, the tab will open but when I click on it, the tab I was on will close (same with most browsers I've tried)

I've tried uninstalling drivers and reinstalling etc. It seems to work better if I just use the laptop itself after reboot but eventually the same problem will happen. I cannot find anything through search engines for a fix or even a case like this.

Any help appreciated.

What is the manufacturer and model of the keyboard and mouse? BT devices do not always connect with Windows and can be a headache to keep connected. If you are not using a BT dongle for the external devices, try that vs. the built in BT.

Thanks for the reply. Keyboard is Logitech K810 and mouse is Sandstrom Bluetooth silent mouse SSHBTM17
I have used this hardware configuaration for at least 12 months without any issues until a couple of days ago.

As previously mentioned I have used the laptop on it's own but after an hour or more it has the same 'issues' using touchpad and buttons. I also have a bluetooth speaker system which may cause conflict but it's been here for over 12 months. I have removed and reinstalled all drivers

I appreciate what you say about dongles rather than BT but this hasn't been an issue until the last week or so...
