The Creator Portal refuses to publish my island and says “You can’t publish while these experimental features are enabled: Experimental Editor Settings”. The UEFN Publishing Report for the same private version says “Experimental features: no issues found”. Two private versions are blocked (8531-3593-1748 and 0479-4804-8190).

What Type of Bug are you experiencing?
Creator Portal
Steps to Reproduce
In UEFN, enable Python experimental setting, then disable it and restart UEFN.
Verse build is clean, the local experimental-settings validator reports 0 invalid.
Create a private version from UEFN (Publishing Report is all green).
Open the Creator Portal > Publish, select this private version.
Expected Result
The Portal validation passes like the UEFN Publishing Report and I can continue to publish.
Observed Result
The Portal shows “Experimental features: You can’t publish while these experimental features are enabled: Experimental Editor Settings”. The uploaded ExperimentalSettings.json has every setting false except ValkyrieExperimentalSceneGraphSetting = true (Scene Graph beta, which Epic announced as publishable). It may be a stale experimental flag (Python was enabled earlier and disabled before upload 0479-4804-8190).
Hi, thanks for the guidance. I checked my project :
Project Settings: only the base Scene Graph system is enabled (Beta Access). Scene Graph Animation, the whole Scene Graph Experimental Features list (every component unchecked), Control Rigs in Verse, UE Redirectors, Gaussian Splats, Python scripts and Inventory are all unchecked. The uploaded ExperimentalSettings.json confirms it: every flag is false except ValkyrieExperimentalSceneGraphSetting (the base Scene Graph system).
Verse source (21 files): no “@experimentalexperimental” and none of the experimental components (fort*component, health_component, hearing/sight/touch detectors and emitters, camera components, creature mesh components, basic_lootable_component).
Every Scene Graph API I use is non-experimental in the project’s digests: entity, component, transform_component, mesh_component, particle_system_component, keyframed_movement_component, basic_interactable_component, and the transform and entity functions.
No prefabs and no entities placed in the level: all entities are spawned from Verse at runtime. No animation or experimental component in any asset.
The Verse build shows no experimental API warning, and the UEFN Publishing Report and the local experimental settings validator are all green.
Despite this, the Creator Portal still says “You can’t publish while these experimental features are enabled: Experimental Editor Settings”. Python scripting was enabled earlier in this project and has since been disabled. Thank you!
