Phlox Core Elements plugin not working

Today the Elementor editor won’t load & keeps bringing up a safe mode option.

I deactivated all the plugins & the editor works again but half the elements are missing.

I then reactivated the plugins one by one & if I activate the Plox Core Elements plugin (the main theme plugin) then it all stops working again.

I have updated the plugin to the latest version & it still causes Elementor to stop working.

It was all fine last week & I haven’t changed anything in that time, so why has it suddenly stopped? I’m now stuck with a half finished website which I can’t edit unless I change theme & start again.
