I know it’s better to use a breadboard, but I don’t have one, so I use my soldering iron.
I checked connections, there is no bad contact or short.

I had an idea to simulate not working rfm module. I unsoldered VCC wire, RFM95 was not powered. In the console I saw:

Starting

C:\Users\lorauser\Documents\Arduino\libraries\arduino-lmic-matthijskooijman\src\lmic\radio.c:545

The message changed. RFM module is working. I soldered the VCC back. I’m back to initial message
