Thanks for your kind response.
As suggested i have performed a full conflict check using Site Health Plugin keeping
all other 3rd party plugins deactivated and just WooCommerce (because issue is related to checkout) and Yoast activated. Theme set to default theme. Issue is still there.
really looking for a quick response as it is damaging our ranking seriously.
Console log for checkout with Yoast activated.
