pyside6-lupdate not work file not found error

[luca lusva]

Hello,
i'm try to create a file .ts for translation.
If i run pyside6-lupdate.exe test.ui -ts it.ts the console give me an error :

File "c:\users\*****\appdata\local\programs\python\python39\lib\subprocess.py", line 1416, in _execute_child
    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

if i run pyside2-lupdate.exe test.ui -ts it.ts everything works correctly.

However if i use .pro file pyside2-lupdate.exe tets.pro lupdate create an empty file.

These are the files

test .ui
