@JOSE RODRIGUEZ​ : I am giving you some options to rule out, you can reply back once you have ruled the below.

1. Try installing other packages: See if you can install other packages using the cluster config GUI. If you're only having issues with XlsxWriter, it's possible that there's a specific issue with that package. If you're having issues with all packages, there may be a broader issue with the cluster configuration or the Databricks platform.
2. Check the logs: Check the logs for the cluster, driver, and worker nodes to see if there are any errors or issues related to the library installation process. This could give you more insight into what's causing the problem.
3. Try a different installation method: If you're not able to install packages using the cluster config GUI, try using a different installation method, such as installing the package via the web terminal or using the Databricks REST API. This may help you identify whether the issue is with the cluster configuration or the library installation process itself.
