It's definitely during the compiler initialization stage that some intrinsic was not found. Is your project open-source? Could you share a repo (you can do it privately in DM, and I will investigate the problem)

[Michael Paus]

Have you tried 1.6.10-rc01 instead of 1.6.10-beta02?

[Zoltan Demant]

@Artem Kobzar Sorry, its closed source. I was able to get it running just now though by removing my design system dependency from it. It was just the foundation layer, so no components, but it does contain compose-resources and has sourceSets: androidMain, commonMain, sharedJvmMain and wasmJsMain. I wonder if any of that could be related?

@Michael Paus Yup, unfortunately rc01 breaks a lot of stuff in my project due to the new compose compiler plugin. Im still investigating, but its largely due to my project for some reason backtracking to kotlin 1.9.23 when I target rc01. It works just fine with the other versions.

@Artem Kobzar It's happening also in my project: https://github.com/typesafegithub/github-actions-typing-editor/actions/runs/9338012318/job/25700627626 - it's open-source so you can investigate

[Piotr Krzemiński]

@Artem Kobzar is there a ticket for it, or should I create one?

[Artem Kobzar]

Hey, I don't see any ticket for it in YouTrack, so, yes, could you please create one?
