Woo Shipping not charged since upgrade to woo 4.5.1

I have have had to disable this plugin since woo upgrade 4.5.0 / 4.5.1

It is stopping calculation of shipping on the basket and no shipping displayed through out checkout. The option is displayed on the basket correctly but once address is entered to calculate it just returns to no boxes and a link to calculate.

I’m using Oceanwp theme and litespeed cache but this has only taken place after upgrade of woocommrce.

Just thought I’d let you know
Thanks
