ERROR MESSAGE: Token StartElement in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment.

This message appeared when working on a project in Trados Studio 2022. I decided to repair the program.

After repair was complete, Trados would not start.

Could you give me some advice as to what to do with this issue?

I have to work on the project right away as it is urget....

Thank you in advance for your help and support.
