RTC sketch problem

I run the RTC sketch without any modification (Arduino Mega) but it resets the blynk connection after it displays the time and date. See output on serial monitor:

Is it possible to use both the blynk RTC and and a DS3231 real clock at the same time?

They seem to use both the same timer functions and conflict…

Strangely enough I have no problem when I include the RTC code in my own sketch.

To use it with my hardware RTC clock, I just used
WidgetRTC rtc2;
rtc2.begin();

to avoid conflict and it seems to function…
