hello?
After the recent update, Export 3D Files of projects that previously worked well do not work.
In my opinion, it seems that complex files are not being exported.
Things that aren't complicated are still doing well.

The 3D view works well on EasyEDA pro.
When I try to export it as a STEP file, it stops after a while, depending on the project.

Looking at system resources,

EasyEDA is barely taking up any resources.

I need to export the 3D file for case design, but it stops in the middle, which is frustrating.

I am not a beginner user of EasyEDA pro.
I have been using EasyEDA pro for over a year and have worked on many files so I don't think I am inexperienced in using it.

How can I solve this problem?

The captured image below was seen in EasyEDA pro 3D viewer.
In this state, if I go to File --> Export --> 3D FIle, it stops after a little progress.

The environment I am using is as follows.
Windows 11
EasyEDA pro V2.1.57
Same symptoms for both installed version and web version
full online mode

Please check and resolve the problem.

Before this V2.1.57 update, even among the projects where 3D FIle Export worked well, some that were considered a bit complicated are not working.

This project, which uses almost similar parts, is normally exported as a 3D STEP file.

I can share or send you the project files I worked on if necessary.
Can I send it to File --> SaveAs --> Project Save AS (Local) with the extension xxx.epro?

Before the recent update, the same project file was exported as a 3D file and imported into Fusion 360.

Now it's stuck in the middle of the process and I can't do anything.

A problem occurred where the background screen did not change in the 2D viewer, which was working fine before, and now the 3D file export function, which used to work well, suddenly does not work.

When an update is made, a function that wasn't supposed to work or needs to be changed, but it's really embarrassing when a function that works doesn't work like this.
