Keyboard & Mouse Unresponsive when first logging in

I've seen a few posts about this on reddit and here but no real solution. I have a USB Keyboard & Mouse that are totally unresponsive when I first login to bazzite after boot up. Sometimes they are recognised and start working a minute or so after login, others I have to unplug and plug back in the KB/Mouse to get it working. Is there a solution to this or does anyone know what is causing it?
