LVGL Crash Error During Project Rebuild in SquareLine Studio

How to

I’m encountering an error while attempting to rebuild my project in SquareLine Studio. I’ve attached a screenshot of the LVGL Python server console for reference. Here’s what I’m seeing:

  1. The project initially loads successfully.
  2. The LVGL server starts and listens on port 20085.
  3. A client successfully connects.
  4. During the ‘Start full rebuild’ process, specifically while ‘Rebuilding all screens’, an error occurs: ERROR: Error: LVGL crashed Please check the console
  5. After this error, there’s an attempt to load ‘screen_global:ui_InputConc_Screen’.

I’ve reviewed the console output, but I’m unable to identify the specific cause of the LVGL crash.

Hi,

On the InputConc_Screen, one of your widgets or events has a parameter set that caused LVGL to crash. You need to find the widget or event on the screen that’s causing this problem. The easiest way to do this is to start removing widgets from that screen and press the “Restart LVGL” button in the header. Once you’ve identified which widget it is, you’ll likely find the cause of the error as well. But if not, send a screenshot of the widget’s settings, and I’ll help you.
