Crash when trying to export ui

What do you want to achieve?

I want to export UI but the software crash when I click “Export UI Files” or “Create Template Project”

To set export path in "Project Settings " but the soft crash when I click browse button…

We need the full log file to see the error. Can you send it to

I am having the same issue. Just started to evaluate the trial v1.2.3
Getting the following error: Segmentation fault (core dumped)
No log file is written.

The crash occurs during the export or while trying to setup the output folder. Regardless of the project created.
I started with an arduino based project, 1 screen and 1 button in the middle… nothing else.
