I get the same issue with IU-252.18003.27 and IU-252.19874.12. Disabling or enabling “Build, Execution, Deployment” > “Debugger” → “Attach coroutine agent” doesn’t fix the problem

Issue still persist with latest EAP 252.23309.22
Run plugin on preinstalled IDE is not proper solution as we need to run it in debug mode (doing so with external attach is possible but tricky) @jakub.chrzanowski may be you have any workaround?
Hm, I’m successfully running 2025.2 EAP 252.23309.22 if I turn off “Attach coroutine agent” in the host IDE.
I’m using 2025.2 eap as host IDE and 2.6.1-SNAPSHOT of the Gradle plugin, haven’t tested with 2025.1. I’m using Gradle properties on the command line to override the IDE version, haven’t tested a custom runIde task.
If nothing works, you can always do remote debugging with an installed IDE.
