There are factors:


1 - Like poor Wifi connection


2 - Slow wifi connection


3 - Too many other people downloading at the same time and Apple Severs are overloaded


4 - Software on the computer interfering with the download process including AntiVirus Software


Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.


5 - Running behind a VPN which may increase Packet losses or corruption of the download 


6 - If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer. 


7 - Best Results are via Ethernet Cable to Router


8 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal and Try Again using the Software Update Applet in System Preferences


9 - Worst case - Restart in Recovery Mode and choose Reinstall macOS. This in theory will pull the latest version of Monterey available and commence the installation.
