So it just doesn't run, no error message or anything? Hmm, I wonder. Please try the following:
1. Check that the required .net version is installed. spritesheetslicer.exe uses .net 4.8 (previous version of spritesheetslicer used .net 3.5). You can run this command in a command prompt:
dotnet --list-runtimes
2. In a command prompt window, run spritesheetslicer.exe. Do you see any output?
3. In the same command prompt, run spritesheetslicer.exe --help. Do you see any output?
