Could it be possible that this is another problem that is not listed. I tried the solution to remove the GetPlayspace calls but I still have an error when trying to publish. It is the same error that occurred when launching session but now it occurs in the verse persistence check.
VerseBuild: Error: C:/build/FortniteGame/Plugins/GameFeatures/…/sys/published/Assets/Assets.verse(56,19, 56,24): Script error 3588: Ambiguous identifier; could be cr1pzzy@fortnite.com.PROJECT_CITY_X.vending.Vending_Blue_material.color or Verse.org.Colors.color
