I picked a process and the following error shows up

./AMDuProfCLI collect --config tbp -o ~/ --pid 8301
ERROR : The driver failed to start profiling. (error code 0x80004005)

my cpu is  Model name: AMD Ryzen Threadripper PRO 3945WX 12-Cores which is in the supported list. I did not see any other error message, even with sudo it is not working. 

Tried the graphical application, same message.

Kernel V: 6.2.0-36-generic #37-Ubuntu SMP PREEMPT_DYNAMIC Wed Oct 4 10:14:28 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

BTW, i downloaded the latest version of the profiler binary from official website amduprof_4.1-424_amd64.deb and this AMDuProf_Linux_x64_4.1.424.tar.bz2
