Website is only ranking on Non-English countries

Hi there,
With the past google November core update, the site is only ranking on non-English countries only. It used to rank on tier 1 countries like the US, Uk, AU, and CA before the update.
So far I have made sure,

• There are no technical issues regarding targetting.
• Content is in English, Written by professional writers. (No grammatical mistakes or something similar)
• No Manual Actions
• No GEOlocation targeting set
• The server is in the US

The website doesn't even show up for its own URLs, and not even on branded keywords. Does anyone have any idea what is happening here? I am literally stuck
