Huge issues with the KB5028997 - need help

I am an ordinary computer user, not a professional, and am having problems sorting this out. I tried to follow the instructions here:

https://support.microsoft.com/en-gb/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

but got error messages I do not understand and now I cannot even re-enable the Windows RE (I must admit i don't really know what this does).

Here is a copy of what is now in my Administrator: Command Prompt

DISKPART> help select disk

Selects the specified disk and shifts the focus to it.  

Syntax: SELECT DISK=<N>
SELECT DISK=SYSTEM
SELECT DISK=NEXT
SELECT DISK=<Path>

DISK=<N>  
            The DiskPart disk index number of the disk to receive  
            focus.  

DISK=<Path>  
            The location path of the disk to receive focus.  

DISK=SYSTEM  
            On BIOS machines, BIOS disk 0 will receive focus.  
            On EFI machines, the disk containing the ESP partition  
            used for the current boot will receive focus. On EFI  
            machines, if there is no ESP, or there is more than  
            one ESP present, or the machine is booted from Windows PE,  
            the command will fail.  

DISK=NEXT  
            Once a disk is selected, this command is used to iterate  
            over all disks in the disk list. The next disk in the list  
            will receive focus. If the next disk is the start of the  
            enumeration, the command will fail and no disk will have  
            focus.  

If no options are specified, the select command lists the disk that  
currently has the focus. You can view the DiskPart index numbers  
for all disks on the computer by using the LIST DISK command.  

Example:

SELECT DISK=1  
SELECT DISK=SYSTEM  
SELECT DISK=NEXT  
SELECT DISK=PCIROOT(0)#PCI(0100)#ATA(C00T00L01)
