reactivate

An event or activity that was previously stopped can be reactivated, meaning it's started again.

When we talk about reactingivate something, like a project or an account, it usually means bringing back to life something that wasn't working anymore. It might have been closed down due to lack of funds or because it just wasn't working out as planned. When you reactivate something, you're basically giving it another try and seeing if it's worth continuing with.
