I did experience a very strange slowdown earlier today, and other odd behavior - first, a massive slowdown and then on a reboot, the keyboard wasn't found. After some tinkering, it's all better now - though I don't know that the tinkering actually did anything.

But no fix :(
There are many fixes, none of which are likely to be incredibly popular. Here’s one: https://elementary.io/

That seems to happen on MacBook Pros when the computer boots or wakes from sleep with the WiFi turned on, but the WiFi router can't connect to the Internet for whatever reason.
Same! On 2 Macs! My external keyboard and mouse stopped working. I thought I was having some hardware or USB issues.
Are you using Logitech keyboard and mouse, by any chance?
That can be symptomatic of always-on VPN. My last employer had an always-on device VPN and it would cause this issue - my MBP would complain no keyboard was connected at times following a wake event, and then reconcile a few/five seconds later.
Apparently Apple runs the same check on startup even to connect the internal keyboard/mouse.
Same, keyboard and trackpad stopped working momentarily.
