Hi, my name is Camilo. Im developer UiPath for two years. Always update the version and dont have any problem.

But this morning (01/03/2023) UiPath community version requiered update with version 2023.2, now my UiPath Studio dont open, and assistant dont connect (i’ve black circle).

Same problem here.
Below the error log, this is happening only in a instance from a VM. My physical laptop has no problems.

How to solve this?
Thank you all.

This is color “black” You can not disconnect “logout” or from studio (dont open) see the account.

Hi @gabrielvandrift same problem here, i hope get fixed

[GANESH_BALAGAM (GANESH KUMAR BALAGAM)]

The Robot Command Line Interface (UiRobot.exe) is a console application which can request to start jobs, and waits for their output. It is a direct client of the Robot service, and communication is done through an IPC protocol.

To make use of the command line arguments supported by Robots, make sure that the UiPath Robot service is running. If not, start it from the Services Microsoft Management Console snap-in.

To make it easier for you to work with command line arguments, navigate to the directory in which the Robot is installed using the change directory command. For example, if you did not change the default location of the Robot, you can use the following: cd C:\Program Files (x86)\UiPath\Studio.

Note: With 2021.10 version i had no problems
