Thank you for contacting Forum support!

The error "E200" is part of the system update error, and I do recommend to update the console.

I need help with system updates on my Xbox One.

The way to remove the insider program linked to the console is to do a
Full console reset.

This will reset the program information linked to the console and set it to a default.

Make sure you know your email and password linked to the account so you don't lose them.

Hope that helps.

Thank you.

Thank you for the response.

Unfortunately, I cannot remove it from the insider program myself as it was not under my xbox live account, it was under the precious owners, whom I bought the xbox from. I cannot boot into the dashboard either as I am getting the E200 boot error. If I
was able to boot into the xbox OS, I could possibly unenroll the device from there.

Is there a way to unenroll the device using the Xbox serial number?

I can agree with this solution. If you're in the insider program, then you have to remove yourself from it. I tried everything else and the insider program removal fixed everything.
