Post Type Switcher Plugin Also Not Supported

I am having the same problem as someone else on here. When I manually installed the Post Type Switcher plugin (was not present when I searched WordPress’s Plugin Library) it appeared to be disabled with no way to activate it. When I tried to activate it, I received this message:“post-type-switcher” has been deactivated, it deletes data necessary to manage your site and is not supported on WordPress.com. I don’t know if it’s because I am using Elementor to build my site or because I am using WordPress.com instead of .org or what the deal is because everyone recommends this plugin but I can’t get it to work.
