Super key only works as Meta after suspend.
What version of plasma / KWin are you running exactly? There has been a bug in 5.8.0 where KWin would confuse modifier states and break the Meta launcher activation but that was fixed in a later version.

I've had this bug ever since the Meta key was changed to Super, roughly 4 months. I'm on Plasma 5.8.4.

A few months ago the meta key was changed from a modifier key to work as a super key, i.e. both as a modifier and as a single key, so we can finally use it to open up the application menu/dashboard.
OK. So on Linux super and meta key are the same thing. That confused me.
Thanks for the update.
