Hi! The correct version of Emscripten for Qt 6.9 is 3.1.70, it has been updated recently in `QtPublicToolchainWasmHelpers`. As for support of JSPI, `-sASYNCIFY=2` should work in Emscricpten 3.1.56. However, in 3.1.59 it got deprecated in favor of `-sJSPI` flag. It is documented here: https://github.com/emscripten-core/emscripten/blob/main/ChangeLog.md#3159---043024. Please note that using JSPI requires enabling it via experimental flag in Chrome.
There is still some work required for Qt to work smoothly with JSPI, but we are on our way to get there.
