I developed a project with 23.12.0
But when I use 22.10.5 version to run the main file, I get : Could not load type ‘System.Activities.TextExpressionBase`1’ from assembly ‘UiPath.Workflow, Version=6.0.0.0
How can I Resolve it

Hi,

Basically, UiPath doesn’t support forward compatibility, it may be difficult to open the project in old Studio. If you can downgrade each activities packages to lower version and re-create porject.json , it might work in old Studio.

@xin.xue,

As @Yoichi suggested, downgrading the packages in the old studio version is the only option.

Thanks,
