B-L072Z-LRWAN1 lorawan example stuck at waiting for LSE ready

Hello, I've tried running and debugging the example project for lorawan end node and it gets stuck at waiting for LSE ready when I debug it using JLink. I also have a custom L072 board with sx1276 and the same thing occurs. The devkit is in working order, there is no hardware issues because it works in arduino lorawan example. ​(https://github.com/GrumpyOldPizza/ArduinoCore-stm32l0/tree/master/libraries/LoRaWAN/examples/LoRaWAN_Join_OTAA)

I also have a WL55JC lorawan devkit and it works fine with the official ​CubeWL

Any idea why the official I-CUBE-LRWAN does not run or any suggestions how to get it up and running?​

Does that board even have an LSE? I don't see it on the schematic.

I think it's labeled TCXO. The other board is a custom board that I designed and it has an LQFP64 L072/L073 and an external 32.768k, the same oscillator as on a nucleo L073 ​
