It's not language, it's experience, network, and having a differentiator that makes potential employers say, "Wow, we need to hire brutus1213 for our team because they have a really unique skill at <X>!" (X could be Kubernetes, deep learning, Erlang, whatever... the more uncommon, the better though.)

To that end, focus heavily on whatever exists in the vertex of what you're good at (which did you like and excel at of those things you did?) and a growth area (example: Python, C++ and the multitudinous ways they continue to be used together in AI etc).

So you have to look at what existing leverage you have and build upon that foundation. It will be very difficult to get a role without getting some hands on experience back first, so where I'd start is, could you step down to become IC at your current job? I'd be more interested to evaluate a candidate doing Python/Kotlin that wants to move into something adjacent than someone in management who just wants to be a dev again.
