Huge number errors when building my project, that suggests it to be a include/path issue. What can I try to fix it?

Hi,

I have a project in stm32cubeide that I have been using and updating for a while and have not had any issues. Now however, I get

10:35:50 Build Failed. 6348 errors, 48 warnings. (took 6s.171ms)

Looking at some of the errors, it ranges from undeclared variables, to not recognising number formats. It looks like a driver or path issue but the paths look OK to me. Cleaning the the project and rebuilding does nothing. Here is a screenshot of some of the errors and the path:

 

 

Any suggestions as to what I could try next would be appreciated.

Take care that the project root folder is on a short simple path, not containing spaces, non-ASCII chars or other difficulties.

HI, thanks for the suggestion but the project root is the same as it has always been (and it has been working until recently - no idea what has changed overnight). It is a

D:\Engineering_Software\STMicroelectronics\STM32F767\Pulse_base_MA3000_w_f446_v4_BACKUP

In your path there is STM32F767 but the screenshots shows STM32F446...

In the 1st screenshot there is #STM32F446RE., Try STM32F446xx

Without # and without RE

I knew it was going to be something simple. Good eye, it was indeed an incorrect symbol. Thanks!
