I am baffled at the error code and I think I found the solution.The .NET 3.5 files are in the ISO (e.g. D:\sources\sxs)
Enabling in Windows features will download and install from MS, same thing.
Look like Windows 11 got a bug with install.esd caused installations and DISM repairs failed after downloaded ISO from Microsoft, Media Creation Tool or Rufus.
Someone managed to get DISM repairs fixed by download Tech Bench ISO from rg-adguard.net contained install.wim.
You can covert install.esd to install.wim in Terminal (Admin):
Get-WindowsImage -ImagePath "D:\sources\install.esd"
Export-WindowsImage -SourceImagePath D:\sources\install.esd -SourceIndex 10 -DestinationImagePath C:\esd\install.wim –CheckIntegrity

After converted to install.wim then delete install.esd and paste install.wim in ISO source folder. Run DISM repair to see if error code 0x800f081f is gone.
