Code crashed site

Hi,

I’ve placed a code in the snippet and activated it – the site didn’t like it and it made my site crashed. Every time I delete the code snippet plugin and reinstall, It just makes my site crash so I want to delete the incorrect code that was placed so that I can still use this plugin but I can’t get into my site without it crashing. Is there a way for you to help me because I have other codes in the plugin that my site needs, I just need to delete the incorrect code that’s making it crash to be able to use the plugin again.

Thanks
