Hello ! In one of my "flow" a very strange error appeared with a fairly simple step.
1st step: run Excel
2nd: Set the active sheets with index 1

and suddenly I get an error namely:
Microsoft.Flow.RPA.Desktop.Modules.SDK.ActionException: Failed to activate worksheet. ---> System.Runtime.InteropServices.COMException: Invalid forward reference, or reference to uncompiled type. (Exception from HRESULT: 0x80028029 (TYPE_E_INVALIDSTATE))

I was browsing the forums and in the search google, but I can't find a solution to this problem.
