It could be key bounce or key chatter.
Which is fixable via hardware or software lvl most times.

just means the keyboard was powered and maybe when you unplugged it, something shorted on its circuits, this is highly highly unlikely, but you never know

yeah, thats why i would go through device Manager and remove them, then replug the keyboard back in to reinstall the drivers. This would be the best bet after testing other ports. Does this particular keyboard have software for it?

There's no software for it no, not that I remember.
I uninstalled all of the drivers and plugged the keyboard back in, it seems to have helped, or Maybe not, lol. still happens. oh well.

sometimes, your pc will misread it after a unplug, it could be because it was in-use while being unplugged that could have froze it, with removing the drivers and allowing it to reinstall it should fix it hopefully, if it doesn't then I would start considering looking for a new keyboard

Glad to hear its working for now, if you need anything else let us know!

Yeah I had my eyes on a new keyboard anyway I guess it's a sign.

It happens for sure, aslong as it gets you through til you truly need a new one then I wouldnt worry about it!
If you were in Minnesota, I could give you like 10 to use lol.
