Hi Team,
The Workflow where i created the task is v2018.2.4(UI Path Studio).
Once I got the Studio updated and I tried to open my workflow in UI Path Studio v2018.3 but at that time I am getting an error as “An Internal error has occured. It is recommended to restart the UI Path Studio”. I am getting this error, even after restarting my System the same error is poping up.
Kindly suggest how to overcome this issue.
An internal error has occurred. It is recommended to restart UiPath Studio.

Hi @Leonardo I can create the blank Project that wont be a problem but what happens to my existing code. If I migrate the Code from v2018.2.4 to v2018.3 then all my projects are throwing error. In that case how to overcome this issue and how to get my existing code.?
When you migrate code from 2.4 to 3 then all your xaml will give errors… you just need to delete JSON file and start adding all related pacakages from your pacakage manager.
also make sure your root folder name should not be “UiPath” .
