Keyboard not working properly

[Believe]

I have a wireless Microsoft keyboard which has till now runned smoothly with my Windows 10.

The last few days I run into this problem: After a while of using the computer, the keyboard will lag and will ultimatly get stuck on one of the keys (sometimes will even get stuck on a combination like ctrl+z)

I restart the computer and the keyboard will go back to running normally.

This happens every few hours.

Things I have tried:

Swiching batteries. Recharging all my recharble batteries
Cleaning the whole inside of the keyboard and pc
Installed the most updated drivers for the keyboard and usb
Changed usb drives.

Any ideas?

Thank you for the help in advance!

I think that you should blow up dust from your keyboard with a compressed air can or a blower

Keyboard has already been cleaned thoroughly. I have removed all the keys this morning and cleaned under them with an alcohol solution
