How do you find video ideas when your niche feels completely saturated?

So in my main niche it feels like almost EVERYTHING unless its completely weird and unique has been done before and at the same time, when you do try something unique it feels like it will instantly flop with it not being what the audience expects on the channel. How do you find ideas for new videos when your niche feels saturated? Do you struggle to create something new or avoid it due to not being pushed out properly when trying a new idea so stick to same old?
