Fault at runtime

The error I get is when linking the code to the firmware.elf.

I’m using PlatformIO, and compiling with gcc-arm-noneeabi 9.2.1-1.1.1. I added uTensor as a library.

The linker does not find the main() function, so it is not a fault at runtime, but at link time.
Do you have a main function defined in your main.cpp file?
And is your path to the main.cpp file (the src folder) added to "includePath": in the file .vscode/c_cpp_properties.json?
