Install python 3.11.0 with py launcher for all users.\r\n2. Invoke `\"py\"` in command prompt.\r\n3. I expect to launch a python interpreter, but got a error as below\r\n   \r\n   ```console\r\n   \u003e\"py\"\r\n   Unable to create process using 'C:\\Python311\\py\"':  The system cannot find the file specified.\r\n   ```\r\n\r\n    \u003cdetails\u003e\u003csummary\u003eDebug output when enable PYLAUNCHER_DEBUG\u003c/summary\u003e\r\n\r\n    ```console\r\n    \u003e\"py\"\r\n    argv0: py\r\n    version: 3.11.0\r\n    SearchInfo.originalCmdLine: \"py\"\r\n    SearchInfo.restOfCmdLine:\r\n    SearchInfo.executablePath: (null)\r\n    SearchInfo.scriptFile: (null)\r\n    SearchInfo.executable: py\"\r\n    SearchInfo.executableArgs: (null)\r\n    SearchInfo.company: (null)\r\n    SearchInfo.tag: (null)\r\n    SearchInfo.oldStyleTag: False\r\n    SearchInfo.lowPriorityTag: False\r\n    SearchInfo.allowDefaults: False\r\n    SearchInfo.allowExecutableOverride: False\r\n    SearchInfo.windowed: False\r\n    SearchInfo.list: False\r\n    SearchInfo.listPaths: False\r\n    SearchInfo.help: False\r\n     -V:3.11          C:\\Python311\\python.exe\r\n     -V:3.10          C:\\Python310\\python.exe\r\n     -V:3.9           C:\\Python39\\python.exe\r\n     -V:3.7           C:\\Python37\\python.exe\r\n    env.company: PythonCore\r\n    env.tag: 3.11\r\n    # about to run: C:\\Python311\\py\"\r\n    Unable to create process using 'C:\\Python311\\py\"':  The system cannot find the file specified.\r\n    ```\r\n\r\n    \u003c/details\u003e\r\n\r\n\r\nI think this error seems to be similar to #95285.
