It depends on a lot of factors.
I think Python is pretty friendly for startes.
I started with Pascal back in the days.
C is nice as it has quite a limited library that you need to learn, but it contains active memory management (no garbage collection), so if you venture to pointers and memory allocation, you have to pay attention. However, C++ is a natural transition from C, when it comes to object-oriented languages and C/C++ is widely used in embedded systems and high-performance applications.
C# has a huge library from Microsoft and 3rd parties alike. Has Garbage Collection, so memory management is easier. Can be quite a versatile tool on the long run.
Java is also used in many places, it's similar to C#, but C# is more modern and refined, so I'd go with C# unless platform independence is a must.
There's Go, Rust, and all kinds of languages. And there's a whole bunch of them that target the Web platform, such as JavaScript, TypeScript, HTML, CSS, PHP, and whatnot.
So it really depends on what you're after. Maybe just start with Python then you'll see how you go.
