parca agent can not profile some user applications

[AshinZ]

when i try to use parca-agent to collect profiling info in a linux machine, it can not profile some applications like my diy cpp program, which looks like a busy loop. In parca, i can just see some kernel info, how can i debug this?
BTF config is open.
version： parca-agent_0.39.1_Linux_x86_64.
kernel version: 5.10.112-005 centos7.
thanks.

It seems that I have also encountered the same problem. I can only view the kernel information but cannot see the information related to the processes. Have you found a solution to this?
