Error is in IntelliJ's event handling system

IntelliJ Platform
1

With 2026.1 EAP I can’t run the runIDE task.

Getting:

Caused by: kotlin.UninitializedPropertyAccessException: lateinit property eternalStealer has not been initialized

those are my values in the Gradle properties file values:

pluginVersion=2026.1.2
# Supported build number ranges and IntelliJ Platform versions to https://plugins.jetbrains.com/docs/intellij/build-number-ranges.html
pluginSinceBuild=261.17801
pluginUntilBuild=261.*
# IntelliJ Platform Properties -> https://plugins.jetbrains.com/docs/intellij/tools-gradle-intellij-plugin.html#intellij-extension
platformType=IU
platformVersion=261-EAP-SNAPSHOT

Using Mac OS M2 Max

I think it is something with the runIde task from the gradle plugin. When running the ui test with the ide-starter the ide start properly.

Can you please try the latest IntelliJ Platform Gradle Plugin 2.11.0?
