This NOT sounds like not loaded DLL of Valentina BECAUSE
In this case you'd have fail on first call Valentina_Init()
But you have come to VDatabase_IsOpen() ...


Please show this part of code

    gdbRef = VDatabase_New
          
    VDatabase_IsOpen( gDbRef )  <<<< I wonder -- at this point gbRef
                                        don't know path ?

    VDatabase_Open( path )
