Hello, @GazTheGoat,
This seems you have changed your template name, Don’t change the template name https://prnt.sc/26d9n9q Parent theme name should be mentioned there.
Did not face any problems with the Elementor plugin installation once set the correct template name.
And then after Installing the plugins you will have to import the demo and I am sure you will not face this issue anymore.
