(Disclaimer: I'm rather nervous that this isn't appropriate for MathOverflow, but given the contents of my question I don't really know a better place to ask something like this.)

Recently, I've been reading a lot about topics in quantum field theory (QFT) and topological quantum field theory (TQFT). I've consulted many previous threads asking for book and reference recommendations (e.g: here from 2010), and I've thoroughly enjoyed learning about this area of math. It's beautiful stuff, but I have a couple of questions after learning more and more about this subject (by "subject", I mean TQFT).

Question(s): What exactly "comes after" TQFT mathematically? What has it been applied to in recent (say, 5-10 but this is not strict) years? Is TQFT still actively researched, or is it a "dead" subject and if so, what new things have been built off of it?

I’ve tried scouring the internet in search of an answer to this question, but I haven't seemed to find a satisfactory one yet. Most of the resources (and papers that I've found thus far) on TQFT are at least over a decade old and all seem to contain the same material, so part of me has been wondering if I’ve been working towards a dead end? This area of math is so interesting that I sincerely hope that this isn’t the case, but I wanted to ask on MathOverflow in the hopes that someone could provide "next steps" after learning about TQFT (by "next steps", things like papers/books to read, new genres to take a look at, lectures to watch, or even some historical remarks are what I'm referring to here). If (hypothetically) there are simply no such resources available, is there a reason for this sudden drop in usage of the subject? What would be better (or more productive) routes to take in that case?

Thanks for the help! A thoughtful answer to this question would be greatly appreciated.
