That you need to learn how to debug it.
Try building a test application on the STM32 and feed the app known good test data. Apply that same test data to the *same* core app built for a PC.
If that works, perhaps it's your inputs to the computation.
Perhaps your measurements are wrong, perhaps you haven't considered the size/range of the values you are using, or at points within the computation. Perhaps you should try adding some instrumentation, or sanity checks during the computations, and look at the telemetry coming back and the raw data the STM32 thinks it's working on, not the data you can see from the other serial ports.
What speed are you running the STM32 at ? What compiler are you using ? What debug tools are you using?
