"An error has occurred" after first launch

studio

#1

After first lauch (regardless of project) every consecutive launch (debug or run) UIPath just shows “An error has occurred” window without executing anything. After rebooting pc it bahaves the same (first launch works, others not). Problem started today (18.08.2018). I’m using UIPath for 2 months without such issues.

#2

After couple of hours it works normally without any actions from my side.
