Not in most of Western and Central Europe. Everyone speaks great English.
It actually can be a problem because most people switch to English as soon as they realize your are not a native speaker, which can make learning harder.

For sure not in France and Spain (outside of tourist areas).
This was my experience. I lived for almost four years in Berlin, and was trying to learn German (I got to A2, which isn't much). But actually getting experience/immersion in German is difficult in Berlin - everyone under the age of 50 speaks good English and switched to that as soon as my first badly-conjugated sentence left my mouth.
I worked for two German companies while I was there, and the entire tech team in both companies did everything in English. This is normal there. In one of them, the (German) CEO gave a townhall speech to the entire company (~1000 employees) in English.
So yes, it's very understandable for the German government to say "you must be at least B1 to live here" but that doesn't recognise the fact that it is perfectly possible to actually live and work in Berlin with no German at all.
It's different in other German cities, apparently. If we'd moved to Munich or Cologne I would have had more pressure to learn German, and also more exposure to it and more immersion which would have helped learn it.
