Cool Definitely not a space thing, which is one of the causes for this error message.

In searching online, I see this post: Error Code 0xc1420121 Couldn’t Install Windows 10 Feature Update

Though it says Windows 10, it applies to Win11, as the error message is the same.

have you tried any troubles shooting on your own? If so, any of those listed stesp (don't download anything they offer to download on their page, just follow the steps in the Basic Toubleshooting section (the mini menu at the top is clickable to take you there directly).
