Given this is what you have done so far without resolution, what else is there to repair it with ?
dism /online /cleanup-image /scanhealth
The component store is repairable.
The operation completed successfully.
dism /online /cleanup-image /checkhealth
The component store is repairable.
The operation completed successfully.
Takes a logn time:

Dism /Get-ImageInfo /ImageFile:C:\Recovery\windowsRE\winre.wim

Worked but only after I created C:Mount

If this had been a normal Win 10 then either a repair install or a Reset would have resolved.
While I'm not familiar with Win Servers, from what I have found, a Reset/Restore is the only option when those Dism cmds and a sfc /scannow fail to resolve.
Why can't you restore that server ?
It may be worth performing a chkdsk /r to see if HDD corruption is the cause of the system not being able to be repaired.
