 * Hi [@high-ko123](https://wordpress.org/support/users/high-ko123/),
 * It looks like there is some other plugin/code using the [TCPDF](https://tcpdf.org/)
   library on your site. Do you know what it is? Most likely something with PDFs,
   like a PDF invoicing plugin?

 * Hi [@high-ko123](https://wordpress.org/support/users/high-ko123/),
 * Could you please update the plugin to the latest v4.3.1 and try again? I’ve added
   some extra checks, so hopefully, now the error will be gone.
 * Please give it a try and let me know.
