Must be a switch that’s packed up. Somewhere around the bonnet edge, probably a push switch. If you can find it it should be simple to join the wires and fool it into thinking the bonnet is shut.

You shouldn't be driving a car if it as a bonnet catch malfunction, because the consequences of an unexpected bonnet opening are pretty dangerous.

My car has two, one either side of the front cross-member, and two latches. If either latch is not fully latched, it shows a warning. The switches are very exposed at the front, to the weather, which can form oxide on the contacts. If you can access the contacts, try cleaning them up, and adding some electrical grease.
