Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT) when opening xlsx file

I have this exception that is driving me crazy.

When I try to open a .xlsx file this way

Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
string v = "path\File.xlsx";
Workbook wb = app.Workbooks.Open(v); //This triggers the exception
app.Visible = true;
Worksheet sh = wb.Sheets[1];

I have this exception

Error: System.Runtime.InteropServices.COMException (0x80010105): Server launches an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))

at MainWindow.loadFile(String v) in MainWindow.cs:line 139

Anyone could give me a solution and why is this happening?

Ps: I'm using Interop library to open Excel.

Edit: Apparently if I set app.Visible = true; it works, but I don't want that the Excel window appears.

 appExcel.Visible = true;
            classeur = appExcel.Workbooks.Open(DB_Path, 0, false, 5, "", "", true, XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
            appExcel.Visible = false;
