i found issue but no idea how to commit so i posting my solution below

in Magento\Customer\Model\Config\Backend\Address\Street replace afterDelete() with below code

     public function afterDelete()
{
    $result = parent::afterDelete();

    if ($this->getScope() == \Magento\Store\Model\ScopeInterface::SCOPE_WEBSITES) {
        $attribute = $this->_eavConfig->getAttribute('customer_address', 'street');
        $website = $this->_storeManager->getWebsite($this->getScopeCode());
        $attribute->setWebsite($website);
        $attribute->load($attribute->getId());
        $attribute->setData('scope_multiline_count', null);
        $attribute->save();
    }else{
		$attribute = $this->_eavConfig->getAttribute('customer_address', 'street');
        $attribute->setData('multiline_count', 2);
        $attribute->save();
	}

    return $result;
}

I think problem is here vendor/amzn/amazon-pay-module/Setup/UpgradeData.php

    /**
     * @throws LocalizedException
     * @return void
     */
    private function upgradeAddressStreetMultiline(ModuleDataSetupInterface $setup)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $row = $eavSetup->getAttribute('customer_address', 'street', 'multiline_count');

        if ($row === false || ! is_numeric($row)) {
            throw new LocalizedException(__('Could not find the "multiline_count" config of the "street" ' .
                'Customer address attribute.'));
        }

        if ($row < 3) {
            $eavSetup->updateAttribute('customer_address', 'street', 'multiline_count', 3);
        }
    }
