Magento ver. 2.4.3-p1 Unable to add to shopping cart.

Magento 2.4.3-p1

PHP 7.4.28

I upgraded from Magento 2.3 to 2.4.3-p1 and now when a user adds a product to shopping cart nothing happens.  No product is added to cart and no error message is displayed (or shown in logs)

I have tried the procedures online

1. Run the additional SQL lines below

UPDATE core_config_data

SET value = REPLACE(value, '<old root URL or domain>', '<new root URL or domain>')

WHERE path = 'design/head/includes';

1. Delete the cache with the command:

rm -rf var/cache/*

Coincidentally at the same time I am no longer able to reindex Catalog search with the error given below, I have tried resetting the index with no change.

Design Config Grid index has been rebuilt successfully in 00:00:00
Customer Grid index has been rebuilt successfully in 00:00:01
Category Flat Data index has been rebuilt successfully in 00:00:00
Category Products index has been rebuilt successfully in 00:00:23
Product Categories index has been rebuilt successfully in 00:00:00
Catalog Rule Product index has been rebuilt successfully in 00:00:01
Product EAV index has been rebuilt successfully in 00:00:04
Stock index has been rebuilt successfully in 00:00:05
Product Price index has been rebuilt successfully in 00:00:06
Catalog Product Rule index has been rebuilt successfully in 00:00:00
Catalog Search index process error during indexation process:
Cannot instantiate interface Magento\InventoryIndexer\Model\StockIndexTableNameResolverInterface

Any Help?

Still have both of these errors in 2.4.5

No idea where to go on this
