A bit strange issue… with Elementor??

Hi.. I love the plugin... it is the only one of its kind...

But for some strange reason, Is having an issue with Elementor...

After installing, I was getting an error in c panel

elementor/modules/dev-tools/deprecation.php on line 304

So I thought it was an elementor issue... (didn't have it before) but still I decided to update to Elementor latest version.... same...
I downgraded to the previous version... same

So I thought... the only thing I have done recently, was to install "Export WP Page to Static HTML/CSS"

could that be related... so I deactivate the plugin, and the error in the c panel log disappear...

Strange right?

But... I love and need your plugin... could you guys check why is this happening?

Thanks in advance
