Startup problems with LoRa868 modules

[sysLINK]

Hello all,

I received my M5Stack Fire yesterday.
In addition, I bought the LoRA868 module.

Without module the device works without problems.
But when I install the module, the device starts only after several presses of the power button and not always.

With the M5Burner I have already installed the current version 1.7.1-fire without problems.

On the board is the No. 2018.2A printed I think that this is the version.

Can someone help me here?

Thanks
