Looking for someone who can fix Google indexing issue

Hi guys,
I need your help and advice. I have a blog where I published around 140 articles (all original content, no AI spam). But suddenly, I see all of them got deindexed from Google. Not a single post is showing now. Only the homepage is indexed.

I’m still getting some traffic from Bing, but Google is fully dead. I didn’t do any blackhat SEO or bad backlink. Most articles were getting indexed slowly before, but now everything has disappeared. I don't have any issues in the Search Console Panel. The site is https://aitechcafe.com/

Is there anyone who can help me fix this?

Me and my team can help. We are inbox away
