org.eclipse.core.internal.dtree.ObjectNotFoundException: Tree element

[staniere]

hello ,
I get this error message when launching Katalon studio.
I initially get this message when launching katalon suite within a jenkins job.
I suspect this problem occurred after launching several katalon commandline at the same time (these katalon are different jobs in jenkins and thus have different workspaces).

What should I do to get rid of this error ?

here is an extract of my jenkins Job :

I found a way to get rid of this error by applying a trick found in this post ! : Cannot open Katalon after latest update

I only had to delete folder D:\Integration\Katalon\config.metadata.plugins\org.eclipse.core.resources
Katalon studio and jenkins jobs are wotking fine now

Is it forbidden to launch several Katalon jobs at the same time via Jenkins ?
