FlutterFlow for Windows Crashing When Opening "Custom Code" Tab

Current Behavior

I’ve been facing an issue for over a week with the FlutterFlow version installed on Windows.
Every time I click (or simply enter) the "Custom Code" tab, the FlutterFlow application closes entirely and unexpectedly.

I’ve already tried uninstalling and reinstalling the application, and also deleting related folders from Windows and reinstalling everything — but the problem persists.

On the web version, everything works perfectly, but I need both environments because I rely on local run functionality, and this crash is seriously affecting my workflow.

the problem happens in any project

Is there anything I can do to resolve this issue?

Thank you in advance.

Hello!

Thanks for the heads-up—I’ll forward this to the engineering team so they can take a look and work on a fix.

Having the same issue also, all started when I updated to flutterflow-6.0.21, before that it was fine. Hope this will be fixed.
