Did you ask if you can move to a different city and work remotely? Even if only 1-2 years, it might really help to boost your German. Moving to Dresden, Hanover, or Hamburg would help. (German HNers can probably recommend a bunch of small cities 1-2 hours away by train/car from Berlin that will use much more German language!) You could come to the office once a week.

Another tip: Always start the conversation in German. If the person switches to English, ask them politely to speak German, and explain that you are studying German. My parents did similar when they moved to the Netherlands 50 years ago. The local shopkeepers were eager to practice English with my parents, but my parents were also eager to practice their Dutch.

That's really good advice, but I found it hard to put into practice because my German was so bad. And German isn't a language you can just hammer out a badly-formed sentence in; word position is less important than conjugation, so if you get the conjugation wrong it makes no sense at all to the listener. I did try this a few times, but everyone lost patience with the painful butchering of their language when they realised their English was a lot better than my German.

I would have moved city, but a: COVID b: my wife also had a job there c: I really loved Berlin and really enjoyed living there

I like the effort! It is more that half of the battle when learning a new language as an adult. What really helped me: Create your own custom Anki deck. Literally, start from zero. Each time you try-and-fail (or think of something that you don't know how to say), write a note to yourself in English/broken German with the sentence/idea that failed. At home, use a translate tool (LLM/Google/whatever) to build the correct German sentence. Next, add it to your Anki deck. Personally, I only add full sentences, never just vocab, because it adds more natural context. Only add real stuff that you will use. On the first day, you have an Anki deck with one card. If you are really motivated, try to add one card per day, but just 1-2 cards per week will quickly improve the deck. Since the deck is so damn small, you can blow through it in five minutes while riding the S-Bahn/U-Bahn trains. And, every single sentence is useful to you. Bonus: Ask a native German speaker about some of your Anki deck sentences. They will probably love to talk to you about the German language because you will be showing your commitment.
