New Airport Error with SDK

I am trying to create a new airport where one exists in reality but doesn’t on MSFS. Bathurst NB Canada. CZBF just an empty field on the program… I have downloaded the latest SDK on C drive…and follow the pop up menus to create a new airport, not update and existing one on MSFS…
There doesn’t seem to be any updated videos that follow this new updated SDK>>

I keep getting this error

error… failed to copy file from.‘vfs://fs.devmode/edition/templates/assetgroups/bgls/airport-empty/ASSETNAME.XM’ to \C:airport test/Bathurst Airport/Packabesources\airport.–\sceneries\CZBF.xml

thanks
