Debug Grafana server

Grafana
1

Hello,
I am trying to debug Grafana Server.
When I run the server, attach delve, after I attach debugger. When I open UI it get stuck (no response). I tried compiling without optimizations (“-gcflags=all=-N -l”) didn’t help.
I also tried directly via IDE (“pkg/cmd/grafana”), when I run in debug it fails with segfault:

API server listening at: 127.0.0.1:40199
unexpected fault address 0xffffffffc1245470
fatal error: fault

I am running linux (kernel 6.1), intel cpu, golang 1.19.5.
