Error in mbed-os-example-blinky

I imported the mbed - os - example - blinky program, revised and compiled, but the following error occurred

Error: Symbol __user_perthread_libspace multiply defined (by /build/mbed-os.lib/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.RZ_A1H.o and /build/mbed-os.lib/rtos/TARGET_CORTEX/mbed_boot.RZ_A1H.o)

So I created a new account and did the same.

However, the same error came out.

what should I do?

But there is no error in other programs

Hi there,

Which board/target are you trying to compile for? Also, are you using the Online Compiler or the Mbed CLI?

If you are new to Mbed, I would recommend taking a look at our quick start tutorials here:
