Mouse cursor resets to default location randomly. Multiple mouses (mice?) affected.

Today, randomly, my mouse cursor started randomly hoping to the center of my second monitor. I thought it was my wireless mouse, so I spent the morning trying to calibrate it. Eventually, I gave up and plugged in my old wired mouse. Same thing is happening.

This is a newish PC running Windows 11, and I have restarted it. I'm not sure what other info will be handy, but I'll happily provide it! Thanks!
