Answer 1

After lot's of debug found that This issue in Magento 2.3.3 Default version.

In order to prevent this bug on 2.3.3, you need to update "vendor\magento\module-store\etc or override :

magento2/app/code/Magento/Store/etc/di.xml and comment to hashGenerator then the store switcher works for logged in customers.

Before

<type name="Magento\Store\Model\StoreSwitcher">
        <arguments>
            <argument name="storeSwitchers" xsi:type="array">
                <item name="cleanTargetUrl" xsi:type="object">Magento\Store\Model\StoreSwitcher\CleanTargetUrl</item>
                <item name="manageStoreCookie" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManageStoreCookie</item>
                <item name="managePrivateContent" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManagePrivateContent</item>
              <item name="hashGenerator" xsi:type="object">Magento\Store\Model\StoreSwitcher\HashGenerator</item>
            </argument>
        </arguments>
    </type>

After:

<type name="Magento\Store\Model\StoreSwitcher">
            <arguments>
                <argument name="storeSwitchers" xsi:type="array">
                    <item name="cleanTargetUrl" xsi:type="object">Magento\Store\Model\StoreSwitcher\CleanTargetUrl</item>
                    <item name="manageStoreCookie" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManageStoreCookie</item>
                    <item name="managePrivateContent" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManagePrivateContent</item>
                    <!-- <item name="hashGenerator" xsi:type="object">Magento\Store\Model\StoreSwitcher\HashGenerator</item> -->
                </argument>
            </arguments>
        </type>

You can find more info about this issue here: https://github.com/magento/magento2/issues/24942

To fix issue, you don't need to remove HashGenerator row in vendor/magento/module-store/etc/di.xml, just set sortOrder="1000 for it, so it will look like:

        <argument name="storeSwitchers" xsi:type="array">
            <item name="cleanTargetUrl" xsi:type="object">Magento\Store\Model\StoreSwitcher\CleanTargetUrl</item>
            <item name="manageStoreCookie" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManageStoreCookie</item>
            <item name="managePrivateContent" xsi:type="object">Magento\Store\Model\StoreSwitcher\ManagePrivateContent</item>
            <item name="hashGenerator" sortOrder="1000" xsi:type="object">Magento\Store\Model\StoreSwitcher\HashGenerator</item>
        </argument>
