iClose(), iTime(), CopyRates() etc. takes seconds and crashes EA and MT4

To start I could find no reference to this error in the MT4 forum. The Closest thing to it is this post. https://www.mql5.com/en/forum/313720. I am removing my comments on the MT5 Thread and posting them here.  I am getting a failure at iTime. The code has been perfectly for a number of years. That is until Version Version 4: Build 1220 13 sept 2019.  MetaEditor Version 5.0 build 2143 sept 13 2019.  By the way  I do not allow upgrades until the build has been out for a while. 2 prevent a update. I run a app that removes any *.png file from webinstall. It replaces it with the build I am using. When I have time I run the new build on a testing pc. It is a windows Ten Pro. 32 GB Intel Xeon CPU E5450 @ 3.00GHZ 2 Processors. It is a older dell 2950 server. I have two other Identical servers that I trade off of. One is a back up. Those two pcs do not have this error. but occasionally lock up.  After reading This thread above  I am not sure it is the Build. I tried as suggested  EventVWR

The Code I am using Traps all errors in a central Place  I call GOD.  GOD Global Operation Debugger . It tracks the errors in every single function Just prior to this error I was using copy rates.I load Three time frames back to back to compare the oanda data to a Reuters data feed specifically Refinitiv eikon core feed .The failure is in the function that deals with error  4066 . I also Track every article I have read on these topics and store them in an array for  reference during debugging. in the code below is a reference to the article I based the coded on

datetime dtError4066()

   //|   Local Variables Initialization                                  |
   bool     bBreak	        = false; 
   datetime dtRetunThis         = 0;
   datetime dtCurrentTime       = TimeCurrent();
   datetime dtCurrentM1Time     = 0;
   datetime dtCurrentTimeFrame  = 0;
   int iError                   = 0;

   //|   Main body                                                       |
    	dtCurrentM1Time     = iTime(msEASymbol, PERIOD_M1, 0);
	dtCurrentTimeFrame  = iTime(msEASymbol, miEATimeFrame, 0);

      if ( dtCurrentTime >= dtCurrentM1Time && 
dtCurrentTime >= dtCurrentTimeFrame )            dtRetunThis = 

else if ( dtCurrentM1Time >= dtCurrentTimeFrame && 
dtCurrentM1Time >= dtCurrentTime )           dtRetunThis = 

else if ( dtCurrentTimeFrame >= dtCurrentM1Time && 
dtCurrentTimeFrame >= dtCurrentTime )         dtRetunThis = dtCurrentTimeFrame; 

else  dtRetunThis = dtCurrentTime;       iError = GetLastError(); 
      if( iError == 4066 ) {ResetLastError(); Sleep(1000); RefreshRates(); } else break; 

//+  Deinitialization  of Function                                    |

Any help I would be most grateful . Thanks PS the bolded section is the failure point. It was late for me last night I posted the code slightly wrong. It has been corrected

Hi, I reported this issue already one year ago to MetaQuotes but never got a helpful response...

On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors before accessing candle/indicator values.
