Drones are vulnerable because they have to transmit a video feed over many miles for a remote operator to be able to control them. And the enemy can easily detect that, and then launch a missile that homes in on that signal. That's why there aren't any stealth drones. Drones shouldn't work against a first rate 21st century military, but Russia has proven in this war that they are not in that group. One way to make a stealth drone is to make it operate autonomously, without sending back a video feed. But nobody is comfortable with that for obvious reasons. The approach the French have proposed for their next gen fighter jet is to have a stealth jet surrounded by a swarm of stealth drones. The pilot commands all the drones, and so any radio links would be short range and therefore hard for an adversary to detect.
