Checkout page Error (required field error come )

check image = https://riocaft.com/1234-2/

The required field keeps popping up so I can’t buy anything, but I’ve filled it all out

This problem comes when all these are filled in at the checkout and the order is placed on the spot. When I give all the options here (street address, city/town, postal code/ZIP, phone) optional, the order is placed success, but the details of all the options are not displayed.

I have disabled all my plugins here but I can’t find any errors there.

In addition, you can see my shipping method in my second picture, but it does not appear when I select the shipping method here. Please help me to solve these two problems

Both these problems exist only on desktop, mobile does not have this problem.
