Thanks for the reply Michael, I had the issue happen again yesterday and ran `sudo libinput-debug-events`, then changed back to i3, run a bunch of shortcuts and pressed a bunch of keys (all of which did nothing) then changed back to the tty only to see that it was registering those keys being pressed.
I'll try running `setxkbmap` and `xev` from a TTY next time the issue occurs to see if it fixes it / gives me any more information. Also another small thing I noticed. To get out of the situation I click the workspaces, but the keyboard only works if I click a different workspace the the one I am currently in, it doesn't do anything (keyboard still won't register shortcuts) if I click the current workspace. modified my i3config to that (i3lock then systemctl suspend), I think it was that at some point and the issue still occurred, but I'll try it out let you know if the issue happens again.
