Firstly, check if your code in app/code/Pstk/Paystack/registration.php is correct.

If that file is correct, let's run the following commands:

rm -rf vendor
composer install
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy -f

If you still facing this issue, looks like your upgrade from magento 2.3.4 to 2.4.5 failed, try the following solutions:

Solution 1: Update the composer.json file specifically the require-dev section with what is written here https://github.com/magento/magento2/blob/2.4.5/composer.json

Then remove vendor folder and run the following commands:

composer install
bin/magento setup:upgrade
bin/magento setup:di:compile

Solution2: Do the following steps:

  1. STAY IN PHP 7.3
  2. composer require magento/composer-root-update-plugin ~2.0 --no-update
  3. composer update
  4. rm -rf var/cache/* var/page_cache/* generated/code/* ; bin/magento setup:upgrade
  5. composer require-commerce magento/product-community-edition 2.4.5 --no-update
  6. composer update
  7. CHANGE TO PHP 8.1
  8. rm -rf var/cache/* var/page_cache/* generated/code/* ; bin/magento setup:upgrade; bin/magento setup:di:compile
