I guess this is one of the more frequent causes - you fiddle with a connector, there is a brief interruption of the connection (a few ms suffice), the driver feels it must supply more current and drives the output up to almost power supply level, then the connection comes back - and poof. An output capacitor makes this even worse.
Professional drivers often have an open-circuit detection and switch off immediately in this situation.
One simple remedy is to have a Zener directly at the driver board, before any connector, with a voltage just a tad above the intended forward voltage of the laser diode (one needs to cut and try). Then no matter what happens, the driver never ramps the voltage fully up. Of course the Zener must have a proper power rating.
Otherwise a large cap, like 10uF ceramic, directly across the diode helps to absorb the current inrush (it should be considerably larger than the output cap of the driver). Of course that may not be a good solution if one wants to modulate the driver. Then a Lasorb is certainly the best choice.
