com.apple.safari.history high CPU usage

I have Safari 14.0.2 installed and every time when I start up my computer a process called com.apple.safari.history is running and my computer fan will turn on (which is not normal) even when Safari is not open. And when I open Safari and go to History I will see no history. But when I close Safari, killed the process and reopen Safari again the history will come back. Is this a known bug? Thanks.

MacBook Air 13″, macOS 10.15

Hello jeffrva,

We see that the process called "com.apple.Safari.History" is using a high percentage of your Mac CPU capability, and we'd like to help!

We have some steps we'd like for you to try that may help resolve what you're experiencing. We recommend checking to see what difference each step takes on that specific process in Activity Monitor: View CPU activity in Activity Monitor on Mac

Install any available updates for your macOS, and install all software updates available in the Mac App Store. Also install all third-party software and plug-in updates.
Clear Safari history: Safari > Clear History.
Empty Safari cashes: Safari > Develop > Empty Caches. If you don't see the 'Develop' option, you can enable it with these steps: Safari > Preferences, click Advanced, then select 'Show Develop menu in menu bar.'
Quit the Safari application and restart your Mac.
Boot into safe mode and check Activity Monitor there. Restart your Mac like normal to leave safe mode afterwards: How to use safe mode on your Mac

Let us know if you continue to experience the same issue.

Thanks for using Apple Support Communities, and have a great day!
