Create the dump, and zip it to the development team.

Have you re-cooked your project first?

The error occurs even in the internal engine, here is the link     https://drive.google.com/file/d/1c8vtOoUqtvz03zccMQsSBSO59ZbgmAWE/view?usp=drive_link

This error pops up immediately, this is a bug in the new version 2023.3.1

there is a solution ?

Any solution? Maybe @Eifert? 

Did you update to to last version of Unreal for Aximmetry?  I mean 5.3.2

Two issues seen here with 2023.3.1:

1. Colorpicker. Anywhere where you want to use the colorpicker, there is a crash indeed. Adjusting manually the RGB values does work.

2. During loading a project, the loading is stuck at loading a newly cooked Unreal file 5.3.2. As a work-around, I can get it to load when loading first another cooked file for the Unreal compound from another project that has worked, and then loading back to the one I need. (Don't select the same file again while it is not loading, as it may induce a crash too). After the Unreal file loaded in Aximmetrry, I saved. After that, it loads each time so far and runs stable. 

Hi,

A patch for Aximmetry, which will address these issues, is set to be released soon.
We apologize for any inconvenience this may have caused.

Warmest regards,
