First thing to try is go into Device manager and uninstall keyboard driver and reboot allowing for OS to install the driver again. Since you said you had been inside notebook to upgrade storage device. It is possible that you disturbed the ribbon cable connecting keyboard to motherboard.

If using external USB keyboard has no problem, your keyboard needs replacing.

I have this issue too.
I have bought a brand new Inspiron 15 5593 on March 2020.
First month, the keyboard works well.
The second month, some keys start to lag sometimes, even in Windows safe mode. Those are B, N, /, left and down arrows.
After 2-3 weeks, I have realized that those keys lag when the laptop gets warm about 15 mins after starting up.
My temporarily solution is to use USB keyboard. It works fine.
