--- Summary ---
My public world cannot be entered since my last two uploads. The uploads succeed in the SDK, but when I join, the client gets HTTP 403 "File forbidden" from the server-side security analysis endpoint for the new file versions and refuses to download the world. An earlier file version of the same world loaded fine the day before, so this is not my account or network. Fully reproducible, on hidden and normal instances, in both eu and jp regions.

--- Client / environment ---

Client Unity: 6000.0.67f1-DWR
OS: Windows 11
World authoring: Unity 2022.3.22f1
SDK: com.vrchat.base / com.vrchat.worlds 3.10.4
Platform: PC / Windows (standalonewindows)
--- What I have already checked ---
  • The world record is not deleted or private: it is public and still has the "system_approved" tag.
  • Version 7 is smaller than version 6, so file size alone does not explain it.
  • The upload itself completes (file, signature, and world update all succeed in the SDK).
--- Request ---
Please check the server-side analysis result for file_041aafa7-760c-488a-87a4-099a5772a5ca versions 7 and 8 and tell me what the scanner flagged, or whether this is a false positive. If needed, please roll the world back to version 6. I can provide the full client log and the Unity Editor.log.
