unable to sample on WSL2

[Filip Andersson]

Hello im trying to use tool on my windows11 WSL, but it is unable to produce any data.

[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.004 MB perf.data ]
writing flamegraph to "flamegraph.svg"
Error: unable to generate a flamegraph from the collapsed stack data

Caused by:
    0: I/O error: No stack counts found
    1: No stack counts found

I installed perf according to the instructions here, building it from microsofts github.
