Network Issues- maybe the internet connection that you are using is not stable at all. Downloading updates or macOS files can be big in size. while downloading the files, if your internet connection is not stable then you will experience the error.

Users who are using Mac with Apple Silicon will need to use this method. For Mac users (Intel inside), I have provided another method below:
Start the process by shutting down your system. Now start your system and hold the Power button until you see the Startup options.
Select your Startup disk and hold the Shift button. You are going to click and hold the Shift button while clicking on Continue in Safe Mode.
Login to your system; you will be asked to log in again. That is it, you have successfully entered the Safe Mode on Mac with Apple Silicon inside.

For Intel, you are going to use this method.
Restart your system. While your system starts again, you are going to hold the Shift button.
Release the Shift button when you see the Login window. Here you will be asked to log in to your Mac.
You will be asked to log in again for the second time. During the second or third login, you will be in Safe Mode.
Safe Mode is one of the easiest ways to install any Update or macOS on your system. Users who are experiencing the “An error occurred while installing the selected updates” on their system can use the Safe Mode to install the update or even the entire macOS without experiencing any error or issue.
