There’s a specific thread on WAW connections’ query, your thread may be moved accordingly (just an FYI).

That said, this is a perfectly fine connection and you would even have time for a quick drink at the lounge. Even a minor delay would allow you to make the EWR flight with no issues whatsoever. All this, needless to say, in normal circumstances. Nobody knows how long the airspace issue is going to last and it’s therefore entirely up to you whether you wish to amend your travel arrangements at this very stage, for extra peace of mind, may I add.
