There has been a specific bug for years where you are knocked back by skills that change your location, you can get stuck in this state for a long time, this comes from the following skills: javelin, clenc, scatter shot, leap, meteor.
I have died from this bug hundreds of times and selected the most revealing ones, where there is absolutely no doubt about what is happening, it was rare to see it before, but time goes by, and more and more people use it to gain an advantage.
Indicative and detailed in the video below.
