Answer 1

Try this -

Change the line 86 of the following file:

vendor/magento/module-checkout/view/frontend/web/js/view/billing-address.js

It should be changed from

if (quote.isVirtual()) {

to

if (quote.isVirtual() || !quote.shippingAddress()) {

Run these commends after making the above change.

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

Now check on the site, Hope it will work!

Please note that you can override this file in your custom module or extension. If you don't want to make these changes on Magento core file.
