Satellite Tracker on ESP8266 issue

I've been trying to make the satellite tracker from the link below but when I run my code, I constantly get an error on the serial monitor.

https://github.com/CactusProjects/SatelliteTracker

I've tried to run the code on a Wemos D1 mini and NodeMCU V1.0 12-F, code uploaded with Arduino EDI 1.8.15 I've got all the libraries and the code compiles normally and uploads normally.

When running I get the following error in the serial monitor

After looking at the error in Arduino EDI "ESP Exception Decoder" I get the following error message but I am stuck at this point.

Exception 0: Illegal instruction

At the moment there is no hardware (sensors, stepper motor) connected to the NodeMCU, I only uploaded the code at first to see if I got this working.

I hope to find some help here.
