php-vcr will break autoload of PHPUnit - phpunit

Question

Enabling php-vcr in PHPUnit bootstrap file breaks the autoloading of class PHPUnit\Framework\ExceptionWrapper
I tried to downgrade PHPUnit to 7.x without success. Removing VCR from bootstrap solves the ExceptionWrapper issue
Here's the beginning of my bootstrap file
require_once __DIR__ . '/../vendor/autoload.php';
use VCR\VCR;
VCR::turnOn();
VCR::configure()->setMode('new_episodes');
PHPUnit configuration file
<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.de/manual/current/en/appendixes.configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Expected: successful tests
Actual:
