Theme acting up

Loads incorrectly after updating to newest version and looks completely strange while trying to edit (can’t upload image but the edit with Elementor site is filled with boxes, dots, x’s and similar. Have tried plugin detective to find any plugin issues without luck. Everything is updated correctly. What is happening? I’m new to troubleshooting and issues on websites so please help.
