Hello,
The other widgets work. But as soon as I install the unlimited time line widget the elementor editor breaks down and doesnt load anymore. If I click on the widget directly in the plugin panel I get the following error. Could you please have a look? I really need this Widget for a website.

Thank you very much in advance!

Kind regards,
Marcy

I solved the issue by deinstalling and reinstalling the newest version of the plugin (an update was not availble in the wordpress dashboard)
