Install Catalina, reinstall

I am having problems with my 2012 imac.

Could I just reinstall Catalina without backing up (I have Time machine).

Will the installer leave my data along and just reinstall the OS?

Thanks Brian

iMac 21.5″, macOS 10.15

Backup Is Not Required:

A backup would not be required. But I'd emphasize you back up your Mac, just incase anything goes wrong after the reinstall.
