HTIT Trackerv 1.1

Hello
I recently got a HTIT tracker 433mhz.
I wanted to install Heltec’s test program with Arduino. Unfortunately I only get an error message.
Why can’t a working program be made available straight away?
Here is the error message.

c:/users/andre/appdata/local/arduino15/packages/heltec-esp32/tools/xtensa-esp32s3-elf-gcc/gcc8_4_0-esp-2021r2-patch3/bin/…/lib/gcc/xtensa-esp32s3-elf/8.4.0/…/…/…/…/xtensa-esp32s3-elf/bin/ld.exe: C:\Users\andre\AppData\Local\Temp\arduino\sketches\6E96E28E30E24BB0B1F43E2416E9CE7E\sketch\Wireless_Tracker_V1.1_FactoryTest.ino.cpp.o:(.literal._Z11OnTxTimeoutv+0x0): undefined reference to `Radio’
collect2.exe: error: ld returned 1 exit status

I hope that someone can help me further.
Greetings
