Koin in library project with Proguard

[nono3551]

Koin in library project with Proguard I created kotlin library project and included:

val koin_ksp_version = "1.3.0"
api("io.insert-koin:koin-core:3.5.0")
api("io.insert-koin:koin-annotations:$koin_ksp_version")
ksp("io.insert-koin:koin-ksp-compiler:$koin_ksp_version")

I am using proguard with this library project. Problem is that when I include obfuscated library in other project I have problems with koin.

Problem 1: When I NO NOT add koin dependencies into my final project I get error:

Problem 2: I Add dependencies to library dependent project:

implementation("io.insert-koin:koin-core:3.5.0")
implementation("io.insert-koin:koin-annotations:$koin_ksp_version")

When I add koin dependencies into my final project I get error:

I imagine you removed Koin and renabled it. Can you also remove the KSP part, just to check?
