World doesn't load with size of 1.8GB

I use a PS5 to play Minecraft on this platform. My world is the size of 1.8GB which is saved to my external drive and cloud storage. However, I experienced an issue with the game not loading. I've tried different troubleshooting methods listed below:

1. Restart PS5
2. Delete/ Reinstall Minecraft
3. Download saved data from cloud or storage
4. Change network DNS server addresses (something I found on YouTube; it didn't make a difference)
5. Closed/ Reopened game
