Error occurred while regenerating the project in STM32CubeMX 6.13.0 after adding a custom folder path.

I'm using STM323H755ZIT6 NUCLEO board, STM32CubeMX 6.13.0 and STM32CubeIDE 1.17.0.

In my scenario, I created a project in STM32CubeMX 6.13.0 and generated the project. After that, I opened this project in STM32CubeIDE 1.17.0 and added paths for external folders in Paths and Symbols. Later, I edited the .IOC file in STM32CubeMX and tried to regenerate the project, but an error popup appeared.

ERROR POPUP

After this popup, I clicked the OK button, and STM32CubeMX showed 'Project Successfully Generated.' However, when I tried to build the project in STM32CubeIDE, it failed to build, and errors appeared, such as:

D:/NAVANEETHAN/CoffeeMaker/DisplayControl/Project/DisplayControl/CM7/Core/Src/main.c:116: undefined reference to `HAL_Init'

D:/NAVANEETHAN/InstalledSoftwares/STM32CubeIDE_1.17.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.1.0.202410251130/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: 

A total of 40 errors were shown, all related to HAL and OS kernel functions.

I attached All errors in Errors.txt and IOC file

anyone support about this issue
Thank you

The file ..\STM32CubeIDE\.project needs to be removed. Reopening the project in STM32CubeMX and regenerating the code will resolve the mentioned issue.
