Sudden CPU High usage

Hi Community, I recently bought an Apple MacBook Air 13" 2019, everything was going awesome until I updated to Catalina, I encountered numerous issue but the one that really bugged me was the sudden high cpu usage issue. It's like I'm working on Firefox or Chrome ( only have like 10 tabs ) and suddenly sometimes the CPU usage sky rockets to 100% ( both cores ), When this happens I have to restart my mac but still it persists on the next startup only goes away after login.


This has happened to me twice now and I'm worried because my macbook becomes hot, Please advice.


Thanks

MacBook Air 13", macOS 10.15
