[Bug]: Cannot read properties of undefined (reading 'startsWith') on KONET custom network

[Bazzixx]

Describe the bug

I encountered an error when using MetaMask with a custom network (KONET).

When switching to the KONET network or accessing the wallet, MetaMask fails to load and shows an error screen.

The wallet information cannot be displayed.

Expected behavior

MetaMask should load normally and display account information without errors.

No response

Additional context

• Network: KONET Mainnet
• Chain ID: 17217
• RPC URL: https://https://api.kon-wallet.com

The issue occurs consistently when using the custom network.

I have already tried:

• Restarting MetaMask
• Re-adding the network
• Switching accounts

But the issue still persists.

This seems related to custom EVM network handling where account or network state becomes undefined.

Severity

High - The wallet cannot be used when connected to the KONET network.
This issue blocks normal wallet functionality.
