Never heard of that happening. I have no idea if there is a danger, but
when you hear a pop and sizzle, not good. I'd turn off the breaker.
Lights and receptacles are often on different breakers so you may be
able to use the computer. Ot use an extension cord.

Switches are easy to replace, usually with just a screwdriver. Lowes is
open today.

Some structures in the USA built during the late 60's contained
aluminum wiring.

I have personally seen such aluminum wires at outlets and switches
break and short to other contacts.

I have also seen copper wires break and very old switches and outlets
fall apart in boxes.
