Aspire XC-895. Laggy mouse and keyboard

Brand new a couple of weeks ago. i5-10th generation processor, 8Gb Ram, 1TB SDD.
The mouse and keyboard are both 'laggy'; keystrokes are missed altogether, or appear after several seconds. The mouse 'sticks' and failed to respond for several seconds. The mouse has the Bluetooth dongle which, as long as it is plugged into a usb port, allows the keyboard to work even if the mouse is switched off.

I am typing this with the mouse switched off and the keyboard is behaving impeccably! Turn the mou o annd aallof garbagge apppees (turn the mouse on and all sorts of garbage appears)

So, it appears Acer's keyboard/mouse combo can't reliably share the same Bluetooth connection. I've tried uninstalling and re-installing; doesn't help. I've tried different accessibility settings; doesn't help. I've tried plugging the dongle into different usb ports; doesn't help.

Can anyone help?

    Well, you live and learn. My Acer mouse/keyboard combo isn't Bluetooth as I thought, it's 2.4G WiFi. There must be some interference with the on-board WiFi, power supply harmonics or something. To SOLVE the problem I have plugged in a 1m USB extension lead and located the WiFi dongle well away from the PC.
    I suspect that is the solution to a lot of the "Laggy mouse & keyboard" cries for help that appear on every computer forum.

    Is it a wireless keyboard and mouse you are using ?? If yes than try to change the batteries of them and check once

    Yes it's wireless and yes I've tried new batteries. No difference.

    The 'fix' I have at the moment is a separate Bluetooth mouse with its own dongle, with the keyboard working fine via the Aspire dongle with the Aspire mouse turned off.

    Try moving the dongle around to different USB ports. That often helps when you are getting radio interference.

    Try use the front panel USB port, see if that will help. Sometimes this will solve poor reception problem, but giving up the precious front panel port.
    If problem persist, I'll change for a set of wired mouse/keyboard.
