Hi @qinxk
This issue could be caused due to some conflict between versions of Segger J-Link SW. It could be the newer install overwrote the old one or maybe just some shared files and broke the older SW.
Try if the following works for you:
Additionally, this problem has been discussed in other posts. Check them it might be useful for you.
Unable to debug using ‘S32 Design Studio for Arm’ and Segger J-Link Classic Base
If the problem persists, contact Segger about this. It is their SW.
B.R.
