[bug] TLS Support is not available (NixOS)

Describe the bug

So recently our Tauri v2 app has started not being able to complete any fetch requests to https endpoints, logging the error Failed to load resource: TLS support is not available.

We've been using the same flake.nix (src) for the past few months and this issue appeared all of a sudden after a system update (nix flake update && nix-rebuild switch)

The system update did not touch glib-networking, which afaik usually includes the TLS stuff. It did, however, bump webkit2gtk_4_1 from 2.46.1 to 2.46.3. That's the only relevent change I can think of.

On the other hand, the flake for this project hasn't changed at all and I haven't updated it in a while, so in that environment it should still be using a slightly older version of libwebkit2gtk_4.1. EDIT: yeah so according to tauri info it's still using 2.44.3 :thinking:

Is anyone else on Nix (or generally on 2.46.3 of libwebkit2gtk_4.1) having similar issues?

Reproduction

Clone https://github.com/gitbutlerapp/gitbutler
direnv allow or nix develop
Run pnpm dev:desktop to start the application, and notice all fetch requests to external domains throw the TLS support is not available error in the console.
