Kotlin 1.4.20 gradle kts issue in IntelliJ

Question

I am facing constant issues with my build.gradle.kts where the whole thing is basically red since I migrated to kotlin 1.4.20. Also, the gradle version is 6.7.1.

Any one face similar issues or is it just me? any workarounds?

when run through the cli, the build works perfectly fine but in IntelliJ, the whole thing is red

Exception in IntelliJ

java.lang.IllegalArgumentException: declarationDescriptor is null for constructor = TypeVariable(K) with class org.jetbrains.kotlin.resolve.calls.inference.model.TypeVariableTypeConstructor
