Random keys act like they're stuck even though they're physically not

I just bought a brand-new laptop a couple of weeks ago with Windows 11 on it but from day 1 I've been having issues with the keyboard. For example, if I hold down the down arrow button or W key too long sometimes, the window start button activates. If I'm casually typing or scrolling on the web, sometimes either shift, ctrl, windows, or fn key (I haven't been able to verify which ones specifically are the issue but it looks like it's different ones at different times) acts like it's stuck so if I click on something, the computer thinks I'm holding down the shift, windows, etc. key + whatever key I pressed. Sometimes I can't even type anything because of this.

If I lock myself out of my account and then log myself back in, it goes away temporarily so the problem only happens when I'm logged in because the keyboard never does this on the sign in screen. Even if I use an external keyboard or even the on-screen one, it still does the exact same thing so it seems to me it's a software issue and not a hardware one. I've tried updating the keyboard drivers and mouse drivers and uninstalling and reinstalling them. I turned off sticky keys and all that but still nothing. The keyboard troubleshooter has found no issue either. Would appreciate any help with this.
