The 48-72 hour window is critical to prevent mold growth as it usually takes 24 to 48 hours for mold to germinate and grow. Once fungus gets a hold on a drywall surface, it can be the breeding ground for thousands of spores and quickly spread in the air around the wall with every passing hour.
Even though drywall is pretty sturdy, it can be significantly damaged if it gets wet for too long. If moisture damage isn't handled right away, the drywall's structural integrity will be compromised, causing it to become soft, weak, and mold-prone.

Drywall mud can take as long as 24 hours to dry for thick applications. The 24-hour drying time recommendation can be applied to nearly all factors. Some manufacturers will bring down that number to 12 hours if a few shortcuts are applied to help speed up drying time without affecting the finished product.
