Windows 10: Stuck on Windows 10 Insider Program Dev Channel Build 21376.1 - why and how do I fix it?

I am a Windows Insider Program Dev Channel participant sitting on build 21376.1 - my PC is not able to run Windows 11 and I am not receiving updates on Windows 10. All I see on Windows Update is the Windows 11 insider preview error pictured below. Everything I've read says with Windows 11 coming out I will move out of the Windows 10 Dev channel into the Windows 10 Preview channel. I would like to be on the latest release of Windows 10 now. Can someone please explain the reality of what I am dealing with? Does this move from the Windows 10 Dev channel to the Windows 10 Preview chann

I did click on it, and selected the "update" option. It did take me to optional driver updates, particularly, my graphics. I'm still not comfortable with whatever it is claiming to discredit the version of Windows, to suggest that I need to update "Windows 10", which it says will no longer be supported, unless it's updated. That is a misnomer and to me, a threat. I wish MS well in trying to eliminate this issue. It's uncomfortable.
