Login Form Giving Error

WP CROWDFUNDING Plugin: https://ww.wp.xz.cn/plugins/wp-crowdfunding/ doesn’t let the forminator login form to display usual error of Account pending approval. Rather we see error which is: An error occurred while processing the form. Please try again
(undefined)

As soon as the WPCROWDFUNDING plugin is disabled, I do see the usual pending approval notice. I have already contacted with WPCROWDFUNDING support & they haven’t responded, can you help?

NOTE: Already activated/deactivated & done with troubleshooting.
Using Forminator Register & Wooocommerce Login page, I do see pending message, so I’ve tried editing your PHP File which is in mu-plugin i.e login_non_approved_error, however, still forms show above mentioned undefined error.

Kindly Help!
