Critical Error on Exporting Snippets

Hello, I was working on a snippet with an export function and deleted it but now I am unable to export any snippet from Code Snippets. I have deactivated/deleted and uninstalled/reinstalled the plugin. Only the export function is giving this error “There has been a critical error on this website. Please check your site admin email inbox for instructions. Learn more about troubleshooting WordPress.”
Can you help?
