Created attachment 472612 [details] scerenshot of the error in Safari console This page contains has a deployed Jetpack Compose WASM project: https://oblakr24.github.io/KMPDatePicker/ (repo: https://github.com/oblakr24/KMPDatePicker) It opens up successfully, however clicking the buttons intermittently causes the exception (see screenshot): RuntimeError: struct.get to a null reference (evaluating 't()') A very similar error happens on this site: https://shreyashkore.github.io/wonderous-compose-wasm/ The error appears to be specific to Safari Technology Preview, and does not happen on other (non-Safari) browsers.

Thank you for the report! Could you please clarify if this worked in any previous Safari versions (such as Safari 17.6 or Safari 18)?

Hi, it did not work in any previous version, as this was the first version of Safari with WASM garbage collection enabled so as to enable Kotlin Compose Multiplatform projects to run in the first place.
