Description with steps to reproduce

1. Create a plugin (test.qml attached)
2. launch the plugin from musescore

if the command is i.e.
"C:/Program Files/MuseScore 4/bin/MuseScore4.exe"
"C:/Program Files/Microsoft Office/root/Office16/EXCEL.EXE"
"C:/Program Files/Everything/Everything.exe"
it works, but
powershell (as environment variable) or "C:/Windows/System32/WindowsPowerShell/v1.0/powershell.exe"
cmd (as environment variable) or "C:/Windows/System32/cmd.exe"
nothing will happen. It won't launch the exe. Musescore log won't show any error, just it won't execute the commands.
I tried with and without admin privileges no difference.
