Guru Meditation Error on TTGO T-Beam v0.7

I have a TTGO T-Beam v0.7 with OLED attached. After compiling with VS Code and platformIO (env:ttgo-t-beam-v0_7) I get the following error after upload and monitor:

Rebooting...

Seems there is a problem on these boards with activating the charge LED. If comment out line 192 and 194 in LoRa_APRS_Tracker.cpp the unit is working again.

  if (powerManagement.isChargeing()) {
  //  powerManagement.enableChgLed();
  } else {
  //  powerManagement.disableChgLed();
  }
