One thing you could look into is body doubling sites like flow club. It doesn't solve the core issue but might help in a small way outside of work hours. Outside of the internet I keep hearing that Pickleball is the most social sport around! Also have you tried hanging out and working at Starbucks (or similar) after some time (weeks) in the same place it's inevitable to start making connections. Also co-working spaces can offer connections, and they usually have various club goings on on notes on the pin boards etc. One thing I do know is that it takes quite a few times / weeks of time turning up to the same place for conversation to start. Hope this is helpful in some way.
