This page is a shared troubleshooting log for common Unity technical errors. Each entry follows a Problem → Cause → Solution format. If you've run into an issue that isn't listed here, feel free to add it! The goal is to build a collective reference that saves the next person time.
Problem
App builds successfully but the scene is blank or shows nothing when launched on Quest.
Cause
The scene wasn't added to Build Settings. Unity only includes scenes that are explicitly listed there, even if the scene exists in your project, it won't appear in the build unless added.
Solution
Go to File and Build Settings - Click Add Open Scenes (or drag your scene into the scenes in build list) - Make sure your target scene is checked - Rebuild and redeploy
