Hi everyone, I’ve encountered the following problem when processes try to start, do you know how to fix it?

Could not start executor. ERROR_INVALID_PARAMETER=ERROR_INVALID_PARAMETER=0x00000057 : The parameter is incorrect.

try to restart the Robot service and UiPath Assistant; if still failing, repair or reinstall UiPath to restore the executor files.

Happy Automation
