UE 4.20p4 ARCore image database cannot build.

I was trying to open the AugmentedIMages, Finally I solved the problem be using the source code version of Unreal. Hope this issue will be corrected in the next version of UE.
Tks.

This solution doesn’t work, because I haven’t the “GoogleARCoreServices” in my .uproject :

{
“FileVersion”: 3,
“EngineAssociation”: “4.20”,
“Category”: “”,
“Description”: “”,
“Plugins”:
{
“Name”: “SteamVR”,
“Enabled”: false
},
{
“Name”: “AppleARKit”,
“Enabled”: false
},
{
“Name”: “GoogleARCore”,
“Enabled”: true
}
]
}
