I have just quick info about updating from 1.9.10 to 1.9.20 (Android/iOS/desktop project). After update I got this error both on Windows and Mac Could not find kotlin native prebuilt windows x86 641.9.20 (Windows) Could not find kotlin native prebuilt macos aarch641.9.20 (Mac) Surely some mistake in my gradle configuration (FAIL_ON_PROJECT_REPOS vs PREFER_SETTINGS with strange info about missinng "ivy" repository). As workaround I used kmp.jetbrains.com template to download those dependencies locally. I hope this helps someone in the meantime.
