Electronics not working during rain is not what the OP is reporting as a bug.
The bug is the DJ booth becoming permanently broken.
During a dance party, when it rains, the DJ booth at the dance party can become permanently broken by the rain, because it's supposed to be an unbreakable object (for dance party events) and cannot be repaired, even when the rain is gone and the dance party is happening on a sunny day.
It happens in my game too. I had to work around it by creating a mod that lets me reset the DJ booth's repair status.
