Keyboard and scroll won't respond until I click something

So, my keyboard and scrolling just straight up stop working for like a solid minute every time I start using them... unless I click the left mouse button first. It’s super weird. Like, if I’m hanging out in Chrome, the window just turns all gray and unresponsive until I give the mouse a left click. Same thing happens when I’m gaming, too. I just freshly installed macOS, so it’s not some old junk setting, and even trying a system restore didn't do anything. I guess I'm just stuck. Any idea what the hell is causing this?

Fixed it: you just gotta make sure the Hotspot mode is actually toggled on in the TP-Link config utility
