Background:
I use multi run in all projects to run linter, typechecks & test runs for the JS code.

Issue
Sometimes IntelliJ reports errors. Also sometimes one of the MultiRun Jobs refuses to start, so I have to start it manually after the overall MultiRun job started.

The last error I picked from IntelliJ was the following:

java.lang.Throwable: Assert: must be called on EDT at com.intellij.openapi.diagnostic.Logger.error(Logger.java:182) at com.intellij.util.ui.EDT.assertIsEdt(EDT.java:64) at com.intellij.openapi.wm.impl.ToolWindowImpl.setIcon(ToolWindowImpl.kt:429) at com.intellij.execution.ui.RunContentManagerImpl.updateToolWindowDecoration(RunContentManagerImpl.kt:421) at com.intellij.execution.ui.RunContentManagerImpl.getOrCreateContentManagerForToolWindow(RunContentManagerImpl.kt:388) at com.intellij.execution.ui.RunContentManagerImpl.getContentManagerForRunner(RunContentManagerImpl.kt:382) at com.intellij.execution.ui.RunContentManagerImpl.getReuseContent(RunContentManagerImpl.kt:357) at com.intellij.execution.impl.ExecutionManagerImpl.doStartRunProfile(ExecutionManagerImpl.kt:208) at com.intellij.execution.impl.ExecutionManagerImpl.startRunProfile(ExecutionManagerImpl.kt:171) at com.intellij.execution.runners.AsyncProgramRunner.execute(GenericProgramRunner.kt:47) at com.khmelyuk.multirun.MultirunRunnerState.runConfigurations(MultirunRunnerState.java:273) at com.khmelyuk.multirun.MultirunRunnerState.lambda$execute$0(MultirunRunnerState.java:76) at com.intellij.openapi.application.impl.ApplicationImpl$1.run(ApplicationImpl.java:295) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1$1.run(Executors.java:668) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1$1.run(Executors.java:665) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1.run(Executors.java:665) at java.base/java.lang.Thread.run(Thread.java:829)
