I share the sentiment. I haven’t used it in a while (at work use different languages and in the last few years my personal coding is only Python script/Jupyter notebook bite-sized), but anytime I hop into it, it immediately "clicks" and gives a comfortable feeling, despite changing over years. A perfect language for medium sized relatively clean and mature personal or small team projects.

Frictionless, pleasant, not thinking too much how to express things (and still managing to write them reasonably idiomatic), tends to support clean encapsulated code, quite rich environment/libraries, great tools (debuggers, profilers), safe, relatively fast, not many foot guns, zero build setup, on small project zero build times, trivial to create good functional simple UI, can get fancy dynamic with reflection when I need "magic".

Basically not many pain points that would make me rage quit and almost everything I'd want is simple to achieve.

C# is my second favourite language, despite it being OOP first. My personal fav is F#.

Same. I think it’s because it’s easy to read and write, and its worst design warts are at least not ridiculous like they are in say JS or Go, where there are massive cons to weigh against the pros. C# just feels like it’s pretty decent across the board instead.

There's no programming-language cozy like Lisp cozy, but I can see myself working quite happily in C#.
