Answer 1

You need to create a patch for it. And it's a local issue.

1. Install package for managing patches in composer:

composer require cweagans/composer-patches --ignore-platform-reqs

2. Create a new patch file using the below command. copy this file (file A) and also copy your vendor/magento/module-directory/Model/Currency.php file (file B). Temporarily create a new folder and move both file A and file B. open the terminal that file location and run the below command.

diff -u Currency.php CurrencyUpdate.php > fix_price_zero.patch

3. Now Copy that fix_price_zero.patch file and create a new folder in root Magento name: patches, paste your fix_price_zero.patch file here.

4. Add the below content into the composer.json file

"extra": {
    "magento-force": "override",
    "patches-file": "composer-patches.json",
    "composer-exit-on-patch-failure": true
}

5. Create a new composer-patches.json file at Magento root and add the below content.

   {
       "patches": {
        "magento/module-directory": {
            "Price hotfix": "patches/fix_price_zero.patch"
        }
      }
    }

6. Then run below command and patch is applied.

composer install --ignore-platform-reqs
