Problem about the compatibility of cuda-gdb 8.3.1 and QtCreator

Hi, im trying to debug my cuda program on QtCreator.
I newly bought a rtx3090 with cuda driver of 11.1, combined with cuda-gdb GNU gdb (GDB) 8.3.1.
But after i added debugger to Qt, it couldn’t recognized as GDB.
I’ve also tried on the elder PC which is cuda 9.2 with cuda-gdb 7x and showed no problem with it.
So is there any compatibility problem between the new cuda-gdb and QT?
Is it too new for QT5.15?
