Isolating Clipboard Across Multiple Threads to Avoid Data Mixing?

System.Windows.Forms.Clipboard.SetText(project.Variables["C_KeyWord"].Value);

instance.WaitFieldEmulationDelay();
// Emulate text entering
instance.SendText("{CTRLDOWN}v{CTRLUP}", 15);

lock(SyncObjects.InputSyncer) // Lock to ensure single thread access to the clipboard
{
    // Save current clipboard content to restore later
    var previousClipboardContent = System.Windows.Forms.Clipboard.GetText();

    try
    {
        // Set the content from your variable 'C_KeyWord' to the clipboard
        System.Windows.Forms.Clipboard.SetText(project.Variables["C_KeyWord"].Value);

        // Wait for the field emulation delay configured in your instance
        instance.WaitFieldEmulationDelay();

        // Emulate text entering with the CTRL+V command
        instance.SendText("{CTRLDOWN}v{CTRLUP}", 15);
    }
    finally
    {
        // Restore the previous clipboard content to ensure the clipboard's original state is maintained
        System.Windows.Forms.Clipboard.SetText(previousClipboardContent);
    }
}

// Lock : True

// Build the file path
var lockFilePath = Path.Combine(project.Directory, "01 - The Base\\01 - Cookies\\The Lock.txt");
// Check if the clipboard is available
if (File.ReadAllText(lockFilePath) == "False")
{
// The clipboard is available, write "True" to lock it
File.WriteAllText(lockFilePath, "True");
}
else
{
// Wait until the clipboard is available
while (File.ReadAllText(lockFilePath) != "False")
{
// Wait for 1 second before retrying
Thread.Sleep(1000);
}
// Once the clipboard is available, write "True" to lock it
File.WriteAllText(lockFilePath, "True");
