Why does xbindkeys not get the thumbwheel mouse buttons of Logitech MX Master anymore?

The action I configured for the thumbwheel is applied when I enter xbindkeys -k and turn the wheel inside the window. However, when I turn that mouse wheel anywhere else, nothing happens. I restart xbindkeys by runnings xbindkeys after killall xbindkeys. I think recently it had some problems but usually turning the thumbwheel worked. When quitting that process and running xbindkeys -n there is no error message. Turning the thumbwheel anywhere while one xbindkey process is running according to the System Monitor does not have an effect. It does not make a difference whether solaar is running or not. I also tried restarting the plasmashell. xbindkeys -k does not show anything when entering the thumbwheel (only when entering a keyboard key) but that is probably normal. How to get this to work, what else could I try to make xbindkeys get the mousewheel turning input again? **It works when xbindkeys-config is running and the mouse is inside it** after pressing Apply but not anywhere else. Under Edit -> View generated rc file the file matches exactly the default config file at /home/username/.xbindkeysrc it still does not work after quitting xbindkeys-config or after running killall -HUP xbindkeys. I then did run xbindkeys --file /home/username/.xbindkeysrc -v and it showed the below error too even after running the killall command a few times it doesn't show that error and **shows the correct config that's in .xbindkeysrc**. It still doesn't work. ----- Previously, I had the problem that xbindkeys-config did not start anymore and xbindkeys -n returned

*** Warning ***
Please verify that there is not another program running
which captures one of the keys captured by xbindkeys.
It seems that there is a conflict, and xbindkeys can't
grab all the keys defined in its configuration file.

I solved problem 1 by opening up /home/username/.xbindkeysrc in a text editor and commenting out everything and then recreating that file by loading one of the saved profiles in xbindkeys-config but changing its settings by entering the configured key again (turning the thumbwheel) which now seems to be a bit different than before. Maybe that is because of some upgrade. I solved problem 2 with sudo killall xbindkeys. Maybe reconnecting with solaar helped.
