========== END OF STACKTRACE ===========
8. Reopen project without deleting library
9. Edit CapsuleMeshAuthoringEditor.cs and
comment this line "return Texture2D.whiteTexture;"
uncomment this line "return base.RenderStaticPreview(assetPath, subAssets, width, height);"
10. save changes and reimport "Text (TMP)" prefab again
11. There is no crash

- Highlighter.Highlight does not find window when using class name as window title
- Highlighter.Highlight highlights a different component when multiple components have the same property path
- Highlighter.Highlight does not find elements in an array or list when the array or list is collapsed
- [URP][NRP] RenderPass, BeginSubPass, and EndRenderPass errors are thrown when Native RenderPass is enabled
- D3D11 swapchain error pop-up appears and the Editor shuts down when Generating Lighting with Probe Volumes present
Resolution Note:
RenderStaticPreview should always create a texture, and not use an internal builtin texture, like when writing "return Texture2D.whiteTexture;" (if so, the texture will be free later and you get a crash if we try to free the engine "whiteTexture"). This should be used instead:
"return Object.Instantiate(Texture2D.whiteTexture);"
