I cannot import STEP files from the "New 3D Model" menu in EasyEDA pro desktop version. I'm using the desktop version. This has been a problem since a recent update. I exported it as a STEP file from Fusion 360 as I have done so far. I can't import in EasyEDA pro desktop version. The situation is as follows. New 3D Model --> Select File --> Nothing appears in the Model list. When you press Save, “Please select file” appears. The file names are all in English and are simple character names such as ESP32H.step. However, when I run the same file in the web version, it is read and imported without a problem. So now I only import the 3D model from the web version and do the rest from the desktop version. However, I am going through a very uncomfortable situation. Please provide a solution to this problem. Also, if I use Korean in the circuit diagram, the output does not work well. If I change the first letter to English, it sometimes displays, but when I export it as PDF, it doesn't show up. We would appreciate it if you could check the multilingual support issue.  It does not appear in the Model List in the desktop version.  If I use the same file in the web version in the same way, it appears in the Model List and is imported normally.
