I want to update a multi-project build to 1.4.0 and cannot get the gradle configuration to work. I keep getting

org.gradle.cache.CacheOpenException: Could not open cache directory a12qv6mvmtxif3x5d88rky5rk (C:\Gradle\caches\6.6\gradle-kotlin-dsl\a12qv6mvmtxif3x5d88rky5rk)

which is caused by

Caused by: java.lang.IllegalArgumentException: org.gradle.api.internal.initialization.DefaultClassLoaderScope@7c5064e5 must be locked before it can be used to compute a classpath!

I tried delting the content of

/build

folders in all projects/subprojects and all caches in

C:\Gradle\caches\

. Found this: https://github.com/gradle/gradle/issues/4823 But to the best of my knowledge, configure-on-demand isn't a thing anymore and I think that i am not using

evaluationDependsOn

I don't know how to proceed from here.
