Can’t add widgets to front page

Hello! Whenever I try to open frontpage widgets menu in customizer I get this error:

I have this plugins installed:

• Autoptimize
• Classic Editor
• Elementor
• Email Test
• Pretty Links
• Webcraftic Cyrlitera – transliteration of links and file names
• WP 2FA
• WP Cloudflare Super Page Cache

What can be the cause? Thanks.
