Problem with the "Klarna" payment module integration with the PShowConversion module

The cause of the problem is that both modules use the same set of libraries, whose code is duplicated in two places in the store, causing code conflicts.

To ensure these two modules work correctly, you need to manually make changes to the PShowConversion module files:
1. /modules/pshowconversion/vendor/composer/autoload_files.php
2. /modules/pshowconversion/vendor/composer/autoload_static.php
In both files, remove the line containing:

'a0edc8309cc5e1d60e3047b5df6b7052' => __DIR__ . '/..' . '/guzzlehttp/psr7/src/functions_include.php',
