Opening a new folder I created within the 'home' directory causes the software to close automatically. However, after deleting the newly created folder, the software can open normally again. Currently, only the 'tutorial' folder can be opened consistently."

Dear Experts, SDM Users, and Developers,


I am encountering an issue where the SDM software runs normally when opening the default "tutorial" folder, but immediately closes ("disappears") when I try to open a new folder I created within the "home" directory. If I attempt to run the software again, a black command-prompt window flashes briefly and then vanishes. Deleting my newly created folder allows the software to function normally again; however, upon reopening, I see the content/message shown in the new window:


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


I have verified that my sdm_tablefile is correct, and even after replacing the contents of the "tutorial" folder with the files from my own folder, the same problem persists.


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