Problem:
Nested shortcode does not work inside elementor modules

Solution:
It seems the Elementor shortcode module you are using is not able to parse the nested shortcode.

Can you please try to follow the following steps:
- Create a new content template using Toolset (in classic mode, do not use block mode) and add the views shortcode to this content templates
- Save the content template and then try to add this content template shortcode to your Elementor's shortcode widget and check if that help you to resolve your issue.
