Google maps behaving erratically and always zooming out

I have a 13-inch MacBook Pro, 2020 edition, with macOS Monterey, version 12.5.1 As of a few days ago, Google maps started behaving erratically: every time I put a cursor on a map (whether using a mouse or the trackpad), the map quickly zooms out, all the way to the map of the U.S.

This happens with all three browsers: Safari, Chrome and Firefox.

Does anyone know what causes this problem and how to fix it?

Thanks!
