It is uncleatr if the download was successful?
If it is in your Applications folder "Install macOS Catalina.app" reboot into Safe Boot mode and run the installer form there.

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and launch the installer.
