Remove the bobbin and bobbin case, and any dust or fluff on them. The bobbin case fits into a bobbin case holder which rotates as the machine operates. It should be easily removed, for example by releasing a pair of clips. It has a sharp point which catches the upper thread in order to engage it with the lower thread. Run your finger over this and if it feels rough (probably due to needle strikes) then smooth it with fine emery. Take care to reassemble it correctly.

Note that some older (especially pre-war) machines have a quite different design of bobbin. This fits in a bullet-shaped shuttle which is thrown through a loop in the upper thread to make each stitch.

This is my temporary solution.

Indentation of bullets isn't quite right.
as you'll see from this list.

You can have a second warning symbol if you like.
