Description
I compiled an app to Wasm, but it crashes upon launch. I think, this is related to Firebase Remote Config (as this issue is similar to #12623) , but frankly, I'm a bit lost how to drill down the problem further, as switching to the latest master flutter version only helped for the issue mentioned in #12623 and then this one appears.
Reproducing the issue
I was able to reproduce it with the example app from firebase remote config.
the error appears as soon as i hit the "fetch activate" button.
Firebase Core version
2.31.1
Flutter Version
3.22.0-43.0.pre.9
