4. 4. Update drivers and change graphics API

   2. Launch with -force-d3d11 (Windows) or -force-vulkan to test another API
   3. Update Unity to the latest patch of your LTS version
   Did this fix it? Yes No

5. 5. Check infinite loops and memory

   Copy steps
   1. Look for while loops and recursive calls in code that runs on load or Play
   2. Close other heavy apps and watch RAM usage while loading the scene
   Did this fix it? Yes No
