Contact form 7 spins with woocommerce enabled

we have a number of forms on the site and recently they stopped working they just spin on submission. Ive updated to all latest version of both plugins and whet through testing all the plugins on the site one by one.

the result was when i deactivate woocommerce, the forms submit fine.

ive downloaded and reinstalled CF 7 plugin manually to see.
ive resaved permalinks

CF7 version: 5.4
Woocommerce version: 5.1.0 however issue existed with the previous version as well, i upgraded to see if it got solved but it did not

in chrome inspector I see these errors
/wp-json/contact-form-7/v1/contact-forms/1813/refill?_locale=user 403
api-fetch.min.js?ver=a783d1f442d2abefc7d6dbd156a44561:2
