No, the Wither cannot break crying obsidian.
Crying obsidian is a unique block that is extremely resistant to damage. While the Wither is known for its powerful attacks, it is unable to break through the protective barrier of crying obsidian.
This makes crying obsidian a valuable material for building structures that need to be protected from the Wither's destructive abilities. It is commonly used in Nether fortresses and other structures that are vulnerable to Wither attacks.
