The screen is black and the Chrome console shows the error Cannot read properties of null reading handle with the call stack pointing to a function called set shader
This could be due to a missing shader.
Possible solution:
In Chrome dev tools make sure that pause on code exceptions is enabled.
Refresh the page.
Once the code pauses on this error, check the call stack a few functions back to find the name of the material which is missing the shader.
Next, in the Luna plugin window check the Assets tab and uncheck the missing shader.
