Esp32 V2 rebooting... and Compiling error 2 today: Mcu.h:10: error: unterminated #ifndef

Hello,

addition:
Hello,

was thinking to use heltec in commercial project… but this is… :
I tried this: LoRaWAN Library doesn´t work
new pull from Github,
new installation,
first, still does not compile in Arduino IDE, compiles with errors in PIO, but then still getting this (on OS X):

I just want to test the example files actory_Test_Wifi_LoRa32_V2 the next error occurs (my board is registered at Heltec):

In file included from /Users/user2/Documents/Arduino/libraries/ESP32_LoRaWAN-master/src/ESP32_LoRaWAN.h:8,

#ifndef McuSet_H\

WIFI_Lorawan example shoes the same error…
