Wardens not knocking back blocking players is tracked in MC-271699, and I am unable to notice any issue with ravager roar knockback. This ticket will be resolved as Invalid because multiple issues are mentioned.
Also, next time you make a bug report please just use machine translation, what you’ve written here is almost unintelligible.
I would be happy to help you, but can you tell me how to reproduce your bug?
