Crashes on several OS and Machines

[DaCoVI]

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

On Ubuntu 25.04, the FlutterFlow web app crashes unpredictably in both Chrome and Vivaldi browsers.
The same behavior was observed in a Windows 11 virtual machine, where the app also crashed intermittently.

A freshly installed Windows 10 system on a separate physical test device experienced another crashes.

Expected Behavior

The app should remain stable on both Windows and Linux without crashes.

Steps to Reproduce

The crashes cannot be reliably reproduced due to their random occurrence.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Hello! 👋

Sorry for the late response. We didn’t find any issues on our side, and your system specifications look more than sufficient to run FlutterFlow smoothly. It might be something related to your internet connection or ISP — could you please check that and let us know if the issue persists?
