Unable to run the application.

[est7]

class com.google.devtools.ksp.gradle.KspAATask_Decorated cannot be cast to class org.jetbrains.kotlin.gradle.tasks.AbstractKotlinCompileTool (com.google.devtools.ksp.gradle.KspAATask_Decorated and org.jetbrains.kotlin.gradle.tasks.AbstractKotlinCompileTool are in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader$InstrumentingVisitableURLClassLoader @68d6ecb9)

It seems to be caused by an update of the KSP version.

Hi @est7!
I'd like to help you with this issue, it seems like you're running into a version conflict.
The error is a known compatibility issue between KSP and Kotlin versions.
To fix this, try the following steps:

1. Clean your project with ./gradlew clean,
2. try downgrading to a stable combination like kotlin = "2.2.20"
   with ksp = "2.2.20-2.0.2", don't forget to change the agp version to "8.11.0", I actually tried downgrading the version myself, and it worked.
   The project maintainer @skydoves might also consider pinning to more stable versions in the version catalog to prevent this issue for other users.
   Let me know if this resolves the issue for you!
