2. create project and try to run it

expected result: new for is running actual result: building hangs. Error occurs: Unhandled exception in thread started by <function KivyConsole.on_enter..run_cmd at 0x0EA33420> Traceback (most recent call last): File "D:\downloads\kivy-designer\designer\components\kivy_console.py", line 658, in run_cmd creationflags=0) File "C:\python\python3\lib\subprocess.py", line 709, in init restore_signals, start_new_session) File "C:\python\python3\lib\subprocess.py", line 997, in _execute_child startupinfo) TypeError: CreateProcess() argument 8 must be str or None, not bytes

fixing of this error leads to another one:
