I have a dead channel with 11k subscribers, what can I do with it?

Hi everyone! I built a channel a few years back up to 11k subscribers, and it's since just died out.

The subject matter at the time was interesting to me, and I enjoyed making the videos. They had decent traction. My highest viewed video has 1.1m views. I received a strike in 2023 that took a while to resolve, and killed the traction of my channel. Once I was clear, ensured it wouldn't happen again, I started posting, and things just weren't the same.

Fast forward to now - I want to revive the channel, but don't know how to go about it. I'd like to change topics, but I'm not sure if there's a good approach to that.

Just want to get some advice from others that may have faced a similar dilemma.

Thank so much!
