I thought it was because of wp-admin htaccess file too, but when I disable wp-admin Folder BulletProof Mode (WBM) nothing happens, I still get the error. It works only when I disable Root Folder BulletProof Mode.
I have no other security log for elementor but this. The only thing I know is that the iniator is /wp-content/plugins/elementor/assets/js/web-cli.min.js, I do not know if it is something. The response status anyway is a 403.
It is not the first time it happens anyway. I had the same problem with other sites.
