Wrong Intellij idea tool window is picked when app is running in new Idea 2026.1

[FoKas90]

I've upgraded Idea recently to 2026.1 and now flutter plugin wrongly pick Debug window tool instead of Run when I am running app.

The log is pretty simple

I have the same issue. I reported it to JetBrains, and they pointed me here. Here's a useful quote from the JetBrains support person:

The Flutter plugin for IntelliJ IDEA (io.flutter) is developed and maintained by Google, not JetBrains. Starting with IntelliJ IDEA 2026.1, JetBrains introduced a new split debugger architecture that changed how tool windows are managed during run/debug sessions. The Flutter plugin hasn't been updated yet to work with this new API, which is why the Debug tool window opens even when you press Run.

+1 i have the same issue

I updated today and now I also have this problem. This needs urgent fixing!

@pq maybe this could be P0? We can't run the app from the IDE, only debug it.

Also, topic-debugging is wrong, as this is not a debugging bug.

Sorry, that is confusing. I've been kind of treating that topic as broadly "execution" but topic-running would be more appropriate. Updating.

As for the issue @helin24 suggested this might be related (if not responsible): #8878

I was able to reproduce this w/

./gradlew runTarget -Pide=Ultimate -PideV=2026.1
