Getting Struct or Pointer from Delegate

[ordinal1]

Hello!
I ran into a problem. I can't solve the following problem. I need the function to return a structure or a pointer to it.
But I get the error Process finished with exit code -1073741819 (0xC0000005) when using a pointer, and the following stack of errors when calling a structure: (If you remove the Pointer and the Structure, the function will complete successfully)

And next:

//Initialize library
Csclink csc = LibraryLoader.create(Csclink.class).option(LibraryOption.LoadNow, true)
        .search(libPath).convention(CallingConvention.STDCALL)
        .load("CscLink");

//My callback
public interface TEnumTransactions{
    @Delegate @StdCall
    void callback(Integer account, Double date, TTransactionInfo transactionInfo);
}

//My call interface
boolean GetAccountTransactions(int account, double firstDate, double SecondDate, TEnumTransactions transactions);

//Struct of TTransactionInfo p.s if I fill the structure myself and send it to another function, everything is done
public static class TTransactionInfo extends Struct {
    public Unsigned16 Size = new Unsigned16();
    public Unsigned16 Kind = new Unsigned16();
    public Signed64 Summa = new Signed64();
    public Unsigned16 RestCode = new Unsigned16();
    public Signed32 LogDate = new Signed32();
    public BYTE UnitNum = new BYTE();
    public Signed32 CheckNo = new Signed32();
    public String Comment = new UTFString(256, Charset.forName("CP1251"));

    public TTransactionInfo(Runtime runtime, Alignment alignment) {
        super(runtime, alignment);
    }

    public TTransactionInfo(Runtime runtime) {
        super(runtime);
    }
}

//Calling func
csc.GetAccountTransactions(16972, 0, 49998, (account, date, transactionInfo) -> {
	System.out.println(...)
});

In addition, I am attaching implementation examples (presumably Delphi, 32-bit library):

//Call function
Function GetAccountTransactions( Account: Integer; DateFirst, DateLast: TDateTime; Proc: TEnumTransactions ): BOOL; stdcall;

//Procedure
TEnumTransactions = Procedure( Account: Integer; When: TDateTime; const Info: TTransactionInfo ); stdcall;

I checked the functionality of these functions via JNA, everything runs successfully there.
