Reproducing compatibility problem in 2024.2

I got a compatiblity error report from the plugin verifier on my plugin marketplace page. I want to reproduce the problem by running the plugin verifier on my laptop, but it can't download the latest version that's complaining about compatibility.

Here's the compatibility error I received:

IntelliJ IDEA Ultimate 2024.2 eap (242.12881.66)4 compatibility problems. 1 usage of deprecated API. 6 usages of experimental API (Restart)
4 compatibility problems
Live Coding in Python 4.11.4 is binary incompatible with IntelliJ IDEA Ultimate IU-242.12881.66 due to the following problems
Class not found (4 problems)
Access to unresolved class PythonCommandLineState (3 problems)
Method LiveCodingAnalyst.start(Project, DataContext) references an unresolved class PythonCommandLineState. This can lead to NoSuchClassError exception at runtime.
Field LiveCodingAnalyst.commandLineState references an unresolved class PythonCommandLineState. This can lead to NoSuchClassError exception at runtime.
Method LiveCodingAnalyst.lambda$startProcess$8() references an unresolved class PythonCommandLineState. This can lead to NoSuchClassError exception at runtime.
Access to unresolved class PythonRunConfiguration (1 problem)
Method LiveCodingAnalyst.start(Project, DataContext) references an unresolved class PythonRunConfiguration. This can lead to NoSuchClassError exception at runtime.

I updated my build.gradle.kts sections to reference the 2024.2 version that's complaining:

intellij {
    version.set("242.12881.66")
    type.set("IC") // Target IDE Platform: IU for Ultimate, IC for community

    // Pythonid for Ultimate, PythonCore for community
    plugins.set(listOf("PythonCore:242.12881.66"))
}
// ...
    runPluginVerifier {
        // Verify against sinceBuild version and current version.
        ideVersions.set(listOf<String>("233.11799.241", "242.12881.66"))
    }

When I run the plugin verifier or the IDE, I get the same error complaining that it can't find the version:

How can I test with the latest version?
