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.

SafeBoot https://support.apple.com/en-us/HT201262

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.
