Google Ads Optimization Expert Needed

I need a one-time optimization for my Google Ads account, which has been running successfully for the past 8 years. The account has a daily budget of ₹1,800, and until last month, it consistently utilized the full budget. However, over the past 15 days, it has only been spending ₹900 daily, with a significant drop in clicks (around 10 clicks per day). I would like assistance in identifying and resolving this issue to restore the account's performance.
