In-game shop big issue

(PC) The in-game store is not working properly. Consider the case of buying a Battlepass

  1. We go to the store
  2. We choose the offer we need
  3. After clicking the “Buy” button, a store loading window appears
  4. Nothing happens after that (apart from the disappearance of the mouse cursor, but it appears as soon as you move it)
  5. When you try to purchase again, an inscription appears - Processing. Please wait

This is followed by a keyboard lock.
Can be fixed by reloading the character

And nothing. No matter what I try to get, nothing happens

Similar issues have been popping up in threads for over a month now.
so, any ideas? besides deleting the game haha
(I tried reinstalling and repairing, did not help)
