How do I troubleshoot CE-100005-6 when downloading a digital game on my PS5?

First, ensure you have enough free storage space on your PS5. If space isn't the issue, try pausing and resuming the download. If that doesn't work, cancel the download and restart it. You can also try restarting your PS5 and your internet router to refresh the connection. As a last resort, try rebuilding the database in safe mode.
