Have you considered a co-working space? It seems like that could get you what your looking for. Beyond that I'd look to get creative around finding ways to get social outside work. A martial arts or social dance class for example. Frankly I think it's much healthier if your coworkers aren't the core of your social life.
FWIW I too had this problem at the start of the pandemic. My solution was to build a gym and workout with my friends 3x a week. Obviously this isn't a solution for your plight in a new city.
