About an error on XAML file

I am a newbie in OpenRPA and while importing a workflow I am facing this error

Do someone know what is the reason of this error and how to solve it?

There is multiple reasons why this could happen. But it looks like you have openflow running in the background ? if so, then you are support to share workflows using permissions, not using import/Export …
Are you exporting using json from openrpa, or using xaml from openflow ? if xaml, try using .json exports from openrpa, since this will contains regional settings also.
