From the encountered issue description it seems that this is an error caused due to UiPath.Excel.Activities package version that you are using.

It was working before?
Did you upgrade recently the UiPath.Excel.Activities package in your process?

Also, check if the same change occurred for the UiPath.System.Activities package version.

Hi @marian.platonov , the process was working before and suddenly it stopped in between. Tried every possible ways but it is showing the same UiPath.Excel.Activities package error.

the process was working before and suddenly it stopped in between.

There is no such thing. Definitely, something changed in the meantime in the Robot/Studio machine or even in the Orchestrator server.

Which is the Studio version?
Provide the project.json file.
