Development setup hangs when updating client.en.yml

I have a discourse development setup running within WSL. This works quite ok for working on plugins.
But today I noticed something weird, whenever I edit the config/locales/client.en.yml file the systems hangs. I cannot even shut it down normally, a “puma” process just hangs and I need to kill it (-9).
It doesn’t happen with any other file. Changing .rb files or even server.en.yml just reloads the application. But with client.en.yml it just gets stuck.

I’m not sure if this happened before. I just started noticing it today. I am working off the stable branch.
