Hello, I am encountering the same issue. The software runs normally when opening the default "tutorial" folder. However, when I try to open a new folder I created within the "home" directory, the application closes ("disappears") immediately. If I click to run it again, a black command-prompt-like window flashes briefly on the screen and then vanishes. Deleting my newly created folder allows the software to function normally again. The problem is accompanied by the error log shown in the attached image/screenshot, which contains the following message:

Simplified log: (For a complete execution log click here.) Error on selecting new data directory: Couldn't change directory to: D:/appdownload/SdmPsiGui-win64-v6.23/home/new

Current working directory: C:/Users/Administrator

Could you please advise on how to resolve this issue? Thank you very much for your help, and I wish you a pleasant day.
