Problem: IDL not generated after successful build

I'm using Anchor 0.31.1, Solana 2.0.25, and Rust 1.88.0 in WSL (Ubuntu).

anchor build completes successfully, but no IDL appears in target/idl.

Tried:

• anchor clean
• Verified declare_id! macro and Program ID
• All dependencies match latest versions
• Rust is updated
• No error shown, just Error: Could not build IDL

Any ideas or solutions appreciated 🙏
