STM32H743 - arm_rfft_fast_instance_f32 not working

Hello, i am trying to do fft with the cmsis library. however i get the followoing error:

C:/ST/STM32CubeIDE_1.19.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.13.3.rel1.win32_1.0.0.202411081344/tools/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -larm_cortexM7lfdp_math: No such file or directory

Why is this? I already checked the DSP box in the Algobuild directory. Also when I try to look in the Manage Software Packs tab in the ioc file, theres no ARM tab?
