I’m encountering an issue with my AutoHotkey script that’s trying to interact with an active Excel application using COM. The script activates a window, waits for it to become active, and then attempts to access Excel. However, I’m getting the following error:

Error: 0x800401E3 - Operation unavailable.

Line#
020: Arkusz := "Arkusz1"
023: Loop
023: {
025: SetTitleMatchMode,2
026: WinActivate,KORONAWIRUS
027: SetTitleMatchMode,2
028: WinWaitActive,KORONAWIRUS,,60
---> 030: Excel := ComObjActive("Excel.Application")
032: Umowa := Excel.Sheets(Arkusz).Range(NR_U n).Text
033: if Umowa is space
034: {
035: ExitApp
036: }
040: Nr_raty := Excel.Sheets(Arkusz).Range(NR_R n).Text
041: if Nr_raty is space

Steps I’ve Taken:
Ensured Excel is running:

Excel is open and the target workbook and sheet (“Arkusz1”) are active.
Checked COM permissions:

Verified permissions in Component Services for Microsoft Excel Application.
Ran Excel as Administrator:

Attempted to run Excel with elevated permissions.
