Repeated crashes on Flutterflow Windows Desktop version after most recent update

[MartinLockheart]

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

Flutterflow is repeatedly crashing during use after the most recent update. It seems to happen most often when I'm trying to input a variable value in the action editor, but it happens seemingly randomly, so I don't know what the exact cause is.

It has happened multiple times during the span of an hour, and that's getting incredibly frustrating.

Expected Behavior

I should be able to use Flutterflow without crashes.

Hi!
Sorry to hear you’re experiencing this issue.

Unfortunately, I’m not able to reproduce the error on my end. It may be caused by local factors such as your computer’s resources or environment configuration.

In this case, I recommend reaching out to support via the in-app chat or by email at support@flutterflow.io. They have the tools and access needed to further investigate your specific setup and help identify the root cause.

Best regards

First thing I did today on Flutterflow. It crashed almost immediately. I was just trying to edit the name of a condition in the action editor.

I set up my task manager on the side so you can see my system's RAM/CPU. It's not crashing because my system can't handle it. This is a Flutterflow issue.

I'm doing a reinstall right now, but this was not an issue until the most recent update, and I haven't done anything that should cause these sorts of issues.

Hello again. Are you experiencing the same issues on the web version?

Although this should not be the main cause of the crash, you could try resolving the error in your conditional statement. The error indicates that the actions to be executed when the result of your conditional action evaluates to false have not been set.

Kind regards

I haven't tried the web version. I did reinstall the desktop version (a much older version is the one available for download on the website) and then I updated it after installation.

I am still crashing periodically after doing a full reinstall, and I am still dealing with some lag when adding text to variables/conditional statements in the action builder (as shown in the video).

I'm in a large project, which I'm sure is contributing to the lag, but having crashes and large resource spikes while entering text doesn't seem like intended functionality. My PC's fan turns on when I enter text into an action name, hah!

And it just crashed again while I was typing a value into a text widget.

The crashing is happening across multiple projects, so it is not a project-specific issue.

That error is there because it's a new conditional action, with no values under it yet. While I appreciate the recommendation, it's difficult to resolve an error when my client is crashing (and if having an unset conditional value is relevant to this issue, then that's a serious bug).

Hello. At the moment for me no more crashing using desktop. Strange but I appreciate 👍
Sorry for you Martin. Hope it will resolve.
