The attached project is made up of CubeMX 4.18.0.
If you open the project after opening the project at CubeMX 4.19.0 and then creating source again, an error occurs.
This is a known issue with MX 4.18.
Please use the import feature in MX 4.19:
Start by creating a new project, selecting the STM32F103C8Tx MCU (as used in your 4.18 project),
then select the menu File > import to import your 4.18 ioc file.
You will need to redo the clock tree configuration that could not be automatically imported.
But, project generation will work fine then.
I will check this issue and come back to you as soon as possible.
