Can you check the python file exists in C:\Users\admin\ACE-Step-1.5.venv\bin\?
I think there is a case where the UI tries to spawn an invalid Python.
I am not able to reproduce the exact condition yet, though.

Actually, the issue is not fully resolved...

This line in generate.ts assumes an undocumented relationship between ace-setup-ui and ace-setup.
So an unusual installation path, such as the path in the above image, can still fail.
