I recommend online classes with Joshua Craig, these are avilable every weekday at 18:00 Paris time, and are open-classes for all levels. Classes on Mon, Wed and Friday are in English. Classes on Tue and Thu are primarily in Polish (with English when helpful or needed).
To register for Joshua's online classes: https://internal-arts-training.com/classes/ - once you have registered, you will be send a zoom link to be able to join.
You can pay for classes here: https://internal-arts-training.com/online-classes-lessons/
Also, make sure to also ask Joshua to join the WhatsApp group, this will allow you to see updates on class cancelations/changes (email or message Joshua add you to the group).
Note also that registered members of the global I Liq Chuan organization can attend weekly online classes with Grandmaster Sam Chin and senior instructors (Saturdays at 8pm). Members also get access to the ILC video library, they can grade, and they get discounts at the international workshops in Paris and around the world.
