If you have an older outdated copy of the installer delete it and empty the trash.
found in your Applications folder, "Install macOS Mojave.app".
Try again your download, if you still have an issue try the App store download from a Safeboot:
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 try again.
You can launch the installer from here as well or reboot as normal.
