runClient task crashes

[RunoLight]

New into MC modding, downloaded latest MDK, latesk JDK, unzipped it, import an project from existing source into intelliJ IDEA, run every task might help (such as genIntellijRuns, prepareRun, buildEnvironment) before runClient just to test an empty mod. So i'm getting...

Execution failed for task ':runClient'.
> Process 'command 'C:\Program Files\Java\jdk-14.0.1\bin\java.exe'' finished with non-zero exit value -1

a little stacktrace from task:

crashreport is attached, in short it says:

java.lang.IllegalStateException: Could not load icon: Image not of any known type, or corrupt
	at net.minecraft.client.MainWindow.setWindowIcon(MainWindow.java:154) ~[forge-1.15.2-31.1.9_mapped_stable_60-1.15-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A}

Gradle and project SDK are both set to the same JDK (14.0.1)

 

I also tried to use https://plugins.jetbrains.com/plugin/8327-minecraft-development <-- this one intelliJ extension to set up a new project for latest stable forge, and still getting the same error. p.s. Environment variables like JAVA_HOME and Path are OK.
