Black screen when entering any world

Hello, I am experiencing a serious issue with Horizon Worlds that started today.

This morning, when I opened the Horizon Worlds mobile app, I received a message saying that my session had expired and I needed to log in again.

After re-logging in successfully, I started encountering the following problem.

When I try to enter any world, the loading process starts normally, but right when the world should appear, the screen turns completely black.

This issue happens on all platforms I have tested including the mobile app, the web version, and the desktop editor preview. 

The problem occurs with every world I try to enter, including public worlds.

The UI appears to load, but the actual scene never renders. Because this issue happens across multiple devices and platforms, it does not appear to be a local device, browser, or network issue.

 The problem started immediately after the forced session expiration and re-login, so I suspect it may be related to account or session state on the server side.

 I have already submitted a report through the Report a Problem feature and wanted to ask if anyone else has experienced this issue or if there are any known workarounds. Thank you.
