Tracebacks are a type of error information (not the error itself). So its very useful for programmers if you provide the whole message it gives, as they tell us the exact problem.

But most likely the error is due to which version of Blender you have. The addon is designed only for version 3.6, whereas the latest is above 4.0. If you downloaded Blender through steam you can switch to it using the betas feature and selecting version 3.6 Stable LTS.

Sorry, that I forgot to add a note about it on the guides.
