There's something fishy about it.

If you want to be sure, please install the latest version of STM32CubeMX and continue with it.

Welcome, @IZapr.1​, to the community!

Regardless of the fact that STM32CubeMX 6.7.0 is already outdated, I restarted my installation of 6.7.0: no USART3 is listed for STM32F103C6T, only USART1 and USART2.

Please describe how you got USART3, with screenshots if you like.

Regards

/Peter

Very interesting, only the medium, high and xl density devices contain a USART3. However, the STM32F103C6T is a low density one and does not have a USART3. Can you please upload a screenshot from Help > About?

Which version of the firmware package are you using?
