Hello，
     I am debugging vmlinux using aarch64 none linux gnu gdb.exe and
encountered the following error. I searched the relevant forums and did not
find a solution to this error. I need your help, thank you!

Follow error log：

The error itself is fairly generic. Would you be able to share your vmlinux? Or does this reproduce
with a vmlinux I can build and try?
