Hello,
Thanks for the video.
I’ve repeated your actions on my test site, there is no such problem. It is strange. But, please try to do the next:
Go to our Plugins Installer and install the Elementor plugin from there – https://prnt.sc/Z26YCVg881u2 , OR go to Plugins from the WP Dashboard > Add new > find and install Elementor
Let us know the result.
Waiting for your reply.
Regards
