WinAppDriver+C# Can't find element in grid in Runtime mode, but find same element in debug (step by step) mode

[romoat]

Hello!
I try to make a sample of automation project (Win32 app) and have a troble.
I have a small form with small table (2 columns, 3 rows).

An I have next C# code to get all elements of this table:

         Collection<ReadOnlyCollection<WindowsElement>> VersionsList = new CollectionReadOnlyCollection<WindowsElement>>();
         ReadOnlyCollection<WindowsElement> y = null;
         int k = 1;
         string DataPath = $".//Custom[@Name=\"Items row {k.ToString()}\"][1]/DataItem";

do
{
y = null;
y = session.FindElementsByXPath(DataPath);
if (y.Count != 0)
{
VersionsList.Add(y);
k++;
Console.WriteLine($"Current state VersionsList: {VersionsList.Count.ToString()}");
DataPath = $".//Custom[@name="Items row {k.ToString()}"][1]/DataItem";
}
}
while (y.Count != 0);

When I run this code in Debug mode (with brake point) and execute all rows in sequence (Step Into or Step over it's doesn't metter) all works excellent.

When I run test not in debug mode it always find elements without last row ("Items row 3").
I try find this element with another code (before the cycle starts):
y = session.FindElementByXPath($".//Custom[@Name=\"Items row 3\"][1]/DataItem")

But i have the same result in both cases (debug and run).

How can I find last row in run mode?

I will be grateful for any help.

Try adding sleep after datapath

Already tried (1, 2, 5, 10 seconds)...
The result is the same.

Can you try pasting the WinAppDriver console logs when ran in Debug mode and when not in Debug?
