Visual Studio Code – inline keyword causes linker error in Clion

I have a strange error concerning the inline keyword, this is just a sample code I wrote:

#include <stdio.h>
#include <stdint.h>

uint8_t inline LIB_MATH_BTT_u8GetMSBSetBitPos(uint32_t args_u32Variable)
{
    uint8_t local_u8MSBSetBitPos = 0;
    args_u32Variable = args_u32Variable >> 1;
    while (args_u32Variable != 0)
    {
        args_u32Variable = args_u32Variable >> 1;
        local_u8MSBSetBitPos++;
    }
    return local_u8MSBSetBitPos;
}

int main() {
    int x  = LIB_MATH_BTT_u8GetMSBSetBitPos(17);
    printf("%d", x);
    return 0;
}

I ran this code on Visual studio 2022 and this was the result:

4

and the same code was run on Clion with toolchain from MinGW and this was the result:

====================[ Build | untitled | Debug ]================================

so I am so confused why the same code was run successfully on Visual Studio 2022 but failed on Clion.

PS. the code worked successfully on Clion if I removed the inline keyword.
