Thank you for your help. Disconnecting all other devices didn't work and using another M or KB than the ones I have is not an option but disabling the config apps did the trick.
I am having the exact same issues as OP was experiencing. I am using a G710+ but was not using any keyboard software (didn't need to). I decided to install the Logitech software to see if maybe installing it would magically solve the problem but it did not. This is incredibly odd and frustrating as I was able to play before and this issue started randomly occuring. Every once and awhile, if I start a game and am able to actually exit out of the window and close the browser, it might work fine (temporarily). Also completely reinstalled out of last chance hope and the problem still existed.
may try this sithian476, Hope this helps, because it had driven me nuts, tried every suggestion on this site and some others. My problem ended up being the unifying receiver on my logitech keyboard and mouse. I had it installed in a rear usb port and never had the first issue with either the keyboard or mouse until BF4, so for most things it works fine there but with BF4 had lag and freeze issues... FIX (at least for me): move the unifying receiver from the rear of the tower, closer to the keyboard. I used the USB extension hub that came with the k/m combo and installed in the same rear port. All is fine now...
