Thanks for this request!!! I don´t know if Czech Hermetics is still active.
I think it is still alive, but it is not functioning in the way it used to. From what I know, the previous translators for the books (Astrid and Mathew) ended up getting cut out of the group. So they are no longer doing the translation work for the books. The latest book, "The Book of Genii" (Pierre de Lasenic) was released in English last year in March, so I know they still likely have some low grade translation going on.
The other hiccup from what I heard online is that there was some legal issues happening between Vodnar Publishing (ie the Czech side of Czech Hermetics) and the people who control Franz Bardon's estate. The rights to publish the "authentic" English translations of IIH, PME, KTQ, and the other Franz Bardon czech-only texts were probably revoked. I have not heard anything concrete on who will get these rights or when these works might be available for the translation. Unfortunately, this means that the direct works of Franz Bardon in Czech, such as "Textbook of High Magic" and "The Initiatory Texts" will not be available in English. However, you can definitely still get them in Czech, which can be valuable to have.
This is all I know from trying to follow the subject over the last 2-3 years or so. I do know that Lukas Louzecky, the editor for Czech Hermetics, is still actively maintaining the actual online shop for Czech Hermetics with new products and supposed books from Franz Bardon's personal library, but the actual appearance of new books is currently dry. There is occasionally a new Czech version of a book from the same Czech occult circles that appears on the Vodnar side about once or twice a year, but I feel these are of limited value for folks in English speaking countries. If you try to ask Lukas, I think he probably will not end up saying much about what is going on there. It is probably more complicated than we would expect.
