After istalling and importing everything, I only see a boxed header as a homepage and no footer. Also get error 500 trying to edit any page with Elementor

Hello, I have installed and activated the theme and all plugins necessary. I chose a specific home page and header and did basic theme customization uploading a logo etc. I only see a boxed header as a homepage. When trying to edit any page with elementor, I get error 500. I uninstalled and reinstalled wordpress, theme, plugins etc 5 times now. Created woo commerce store, categories and brads twice. I even downgrades wordpress to 6.7.2 in case the theme wasn't compatible with 6.8.1. I followed all intructions in documntation and at thiw point don't know what else to do.
