Now that you have Windows 10 back again, I would suggest ignoring advice from Microsoft to "upgrade" to Windows 11 at least until support for Windows 10 ends. There is a way to block automatic "upgrades" to Windows 11 using a registry entry. It is method number 4 at the link below:

Note that you should set the value to 22H2 now, as indicated by the second link, if you decide you add this Registry entry.

There are other free imaging tools available also, in case you want to try a different one.
