Google crawl and impression-related core issues need to identify

We are seeking a Google SEO expert to help us address the following issues: 1. We have 45K indexed pages on Google for a new website that had 2,300 keywords three months ago. To prevent search result pages from being indexed, we submitted two removal requests on Google Search Console (GSC). 2. When we realized these requests were negatively affecting our indexed pages, reducing our rankings, and removing all keywords from our rankings, we cancelled the removal requests. 3. Despite this, the site's daily impressions have not increased beyond 180 for the last 40 days, whereas previously, GSC showed 6,700 impressions per day. 4. Do you have expert knowledge in this area? How can we resolve these issues? Please review the attached screenshots before applying for this position.
