How can I cleanup faulty PHPsnippets injected via the plugin

https://projectdmc.org/support/topic/delete-faulty-code-snippets-from-the-plugin/

I ran into the problem same as the topic shown above.

In my case … I try to inject php snippets and it’s crash my whole site (code that try to change currency symbol in woocommerce) … unfortunately, safe mode doesn’t work this time … so I decided to deactivate all plugins in database table. Now it’s back to normal.

BUT Here’s the problem

If I still using WPcode again (just only activate plugin) … that faulty code will be active … and boom … crash again

My only option now is NO LONGER use this plugin or talk to developers …

So, How can I cleanup that faulty php code without activate WPcode plugin? Pls. Help

Thank you

Here is the code

add_filter('woocommerce_currency_symbol', 'change_existing_currency_symbol', 10, 2);

function change_existing_currency_symbol( $currency_symbols) {

     $currency_symbols['ZMW'] = 'ABCD';
     
     return $currency_symbols;
}
