UiPath InternalError

I got the following error in UiPath Studio after copy and pasting some flowcharts around:
An internal error has occured. It is recommended to restart UiPath Studio.

When i click ok, it goes to an empty flowchart and whenever i try and click somewhere the error appears again. So it seems i have lost all of my work. Is there any way to recover it?

I have tried saving the axml file to a new file and opening it, as suggested on a another post in this forum.

maybe different versions of UiPath

“Value cannot be null” tells me you created some variable where the name of it was empty, or something like that. Technically, you can probably repair the .xaml in a text editor, but this isn’t something that is recommended if you don’t know what you are doing.

If you want, you can upload the workflow and maybe someone can identify the issue of the file. Otherwise, escalate the issue with UiPath Support: https://www.uipath.com/company/contact-us/contact-technical-support
