Learnpress woocommerce and stripe

Hello guys,
i hereby come to ask some help.

I use learnpress and woocommerce to sell courses on my website.
I cannot use stripe for payment because i have the following error:

PHP Fatal error: Uncaught Error: Call to a member function is_required_enroll() on bool in /var/www/html/wp-content/plugins/learnpress/inc/user/abstract-lp-user.php:2418\n

We will assume that we can make payments via woocommerce paypal gateway.
The issue is related to woocommerce stripe gateway.

We also assume that there is another shop on my page where we sell subscriptions and payments via stripe do work.

The issue is certainly learnpress -> woocommerce -> stripe.

Thanks in advance for your advices and your help.
