Hi,
The error indicates that Joomla extracted the installation package successfully but couldn't copy the component files into the installation directory. This is usually caused by incorrect file/folder permissions, ownership, an existing incomplete SP Page Builder installation, or insufficient disk space.
Please check the folder permissions and ownership for your Joomla installation (especially the components and tmp directories), ensure there is enough free disk space, and try the installation again.
You can take help from your hosting administartor.
Thanks
