9R is TSMC Fab 14 in Taiwan, for STMicro

Pull the PCN from Digikey's STM32G071GB page

This STM has strange functioning after an update, this STM is connected on an Eletronic speed controller and not working after updates.

I've attached an printscreen of programmer.

You'd need to work with the vendor more directly to understand if this is the correct firmware, applied appropriately.

You could dump/inspect the FLASH via STM32 Cube Programmer, making sure it's got the binary data, and hasn't written the .HEX as ASCII into the device.

I don't see anything from your presentation so far that the part is not legitimate, but you'd need to check the circuit / PCB to confirm you're working with the right firmware.
