Memory Profiler load failure in IDEA

What happened

1. Create a new Flutter Project using IntelliJ Ultimate
2. Open Android Emulator (haven’t tried iOS)
3. Run/Debug Flutter project
4. Builds fine, then deployed to app
5. When app is launched, see Exception pop up in IntelliJ.
6. Perhaps related? Unable to see the Widget tree in the Flutter Inspector.

Solutions Tried / Other bits

1. I tried disabling the --track-widget-creation option. No effect.
2. Everything seems to be working, except the Widget tree (setting break points, performance view, etc).
3. No errors received in Android Studio, Widget tree shown.
4. Tried Beta / Dev / Master branches, none worked.

Overall, I’d love to use IntelliJ Ultimate instead of Android Studio, since I work in a few different languages and it’s a pain to constantly switch IDEs / reconfigure all settings / etc.

Well, it shouldn’t crash like that so actually, thanks for the catch!

We should rule this out as a general issue, or address in the M31 timeframe.
