Hi, 
I have just installed STM32 Cube IDE 2.0.0 for Mac OS Apple Silicon, and then installed the GCC ARM for STM32 10.3-2021.10 toolchain through the toolchain manager. However when I import a project using this toolchain I get the nullgcc error.
I also tried creating a new project and setting the toolchain to 10.3-2021.10 but still get the same error.

When I look into the eclipse plugins folder searching for the toolchain binaries, I only see a .jar file but not the actual compiler folder with the binaries
 

ls -l /Applications/STM32CubeIDE.app/Contents/Eclipse/plugins/ | grep gnu-tools-for-stm32
