Unable to cast object of type

Hello, all

I’m facing below error message when i start the process

Is there any one who knows how to solve it?

We would recommend to share with more details on what was done / implemented. So we can better understand the source throwing the exception.

In gerneral the exception looks like issued from internals. Therefore we would recommend tu bring the relevant packages e.g. UiPath.System.Activities to newer version, if not already done.
