I upgraded WSL from Ubuntu 18.04 to Ubuntu 20.04, cmake and make again and now it works.

I am afraid I have to open this again. I am getting it again after pulling the latest version (git pull) then doing the git submodule update --recursive, cmake and make as indicated in the README.

It is an issue of quicly: h2o/quicly#516

Thanks for updating this issue. I will monitor the linked ticket and update qperf once and update in quicly is available
