Sudden increase in Compute time for Serverless Functions daily usage

I see a sudden increase in credit usage this month while traffic and no of requests stays same and even lower than previous month.

Specially I see 4X-5X spike in Serverless Functions daily usage - Compute time and not sure why? (See screenshots below)**
**
There is no major release between last month and this month.

I also raised email ticket May-23 but no response yet.

Please help me understand what is causing this sudden increase in compute and credit usage?

Let me know if any details are required.
