Executeparameter was not selected, we get to see information only on the PEBuild. One thing that sticks out the most is that the Task was created using Win10 Ent x64 1809 with a UBR or 17763.1, but OSBuilder will look for the latest version of the Operating System. In this case it has selected the one with a UBR of 17763.55. So there is no need to modify or change Tasks after they have been created, they should continue to work from month to month.
New-PEBuildagain with the Execute Parameter. Within a few minutes, you have a complete build of WinPE.
