New "Experimental Speed up" casues issues in similator

[conULTRA]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When running the app with Local Run on the iOS simulator, the simulator crashes immediately when an authentication action is triggered (Google login or email signup). The simulator is terminated without any visible error message in the console. The only message shown is “Lost connection to the device.”

This issue occurs when the “Experiments Speed Up BETA" is enabled in Local Run settings. Disabling the “Experiments Speed Up BETA” experiment prevents the crash.

Expected Behavior

Authentication actions should complete normally and should not cause the app/simulator to crash when running locally on the iOS simulator.

Steps to Reproduce

1. Enable the experiment "Experiments Speed Up BETA" in Local Run settings
2. Run the app on the iOS simulator using Local Run
3. Click on the Google login button or try to sign up using email
4. The app crashes and the simulator loses connection to the device

Hello!

Could you please share any crash logs you might have? Sometimes when the app crashes and loses connection, macOS shows a crash report popup. If you saw that, it would be very helpful if you could share the log with us.
