Have any full time YouTubers ever gotten sick of their audience and started a new channel without telling anyone?

For context I have a fairly successful channel and Im thankful for it. I started really blowing up about 2 years ago when I stumbled into my niche playing one game in particular so I kept doing that and it got me to the point where Im able to do this full time.

But Ive now been playing the same game for like 2 years now, and I feel trapped. Its not a new game either with regular updates, its an older popular game and I am just completely tapped out of fresh ideas and frankly just bored of it. But no matter what I do any video that is not this game absolutely tanks in views compared to my main game. And when a new game finally came around that I actually did start getting decent views on, 90% of my comments are just "when are you gonna play X game again" and it feels like Im just forever teathered to my main game.

Im thinking of starting a new channel from scratch, telling nobody and just keep doing my main game on my current channel to pay the bills. Im curious if this is just something every full time youtuber goes through, and if this is something you guys do, or if theres some other insights.
