So what is the issue...
It does not download?
It downloads but you can not launch or install?
Is this a fresh copy of the installer or an old copy?
Did you try again(?) Delete the installer from the Applications folder "Install macOS Catalina.app" and empty the trash then try again.
I would advise to reboot into SafeBoot Mode and re-download the installer and launch the installer from this same SafeBoot mode —Try a 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 proceed:

—A "could not be verified" is often an outdated installer
—A corrupt download is often a function of a slow or suspect Network download speed.
You can try a faster Network,
you can try moving closer to the router,
you can try a cabled Ethernet connection bypassing wireless
