ESPNtpClient library causes restart at NTP.begin(); with core 3.1.0 and not with 3.0.7

[ednieuw]

I use the library ESPNtpClient to update the clock in an Arduino Nano ESP32

The sketch it is used in worked well with Arduino core 2.0.18 and with Espressif core 3.0.5 and 3.0.7.
But with core 3.1.0 that Nano restarts when calling NTP.begin();

I tried to increase the buffer size in xTaskCreateUniversal in the begin() function of the library but that was not the solution (-:.
It is probably a too small allocated buffer somewhere.

It probably has a cause with changes in the WIFI coding. Tried many variations in my code.
Restarting is over if WIFI is not started.
The LEDs on the board also behave strange.

I will wait for a new release and fall back to 3.0.7
