My customize working properly but when using acumatica software for more than a week. the customize stop working

Only this block code:

    // Acuminator disable once PX1008 LongOperationDelegateSynchronousExecution [Justification]
    // Acuminator disable once PX1013 PXActionHandlerInvalidReturnType [Justification]
    [PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "Activate", MapEnableRights = PXCacheRights.Delete, MapViewRights = PXCacheRights.Delete)]
protected void Activate() => PXLongOperation.StartOperation((PXGraph) this, (PXToggleAsyncDelegate) (() =>
{

  if (current != null && current.Status == "V")
  {
    int? nullable = current.UnBillAccount;
        // Acuminator disable once PX1050 HardcodedStringInLocalizationMethod [Justification]
        nullable = nullable.HasValue ? current.UnEarnAccount : throw new PXSetPropertyException("Invalid UnBillAccount", PXErrorLevel.Error);
