Some icons don’t display and elementor is not working properly

Hello there, I wrote some days ago about a problem I had in displaying elemtnor icons, and that elementor didn't open at all from the backend. I had to export and reinstall a new demo from scratch. At first everything worked fine, a couple of days after I've done this reinstall the icons disappeared again and elementor won't work again. It worked fine beacause I set a custom font just a couple of days ago. I'll attach a screenshot of the errors I'm getting, can you please help me figure this out. i'll also leave admin credentials.
