When it happens docker+wsl become completely unresponsive anyway though. Stopping containers fails, after closing docker desktop wsl.exe --shutdown still doesn't work, only thing I've managed to stop the CPU usage is killing a bunch of things through task manager. (IIRC I tried setting a cap while trying the hyper-v backend to see if it was a wsl specific problem, but it didn't help, can't fully remember though).

This is the issue that I think was closest to what I was seeing https://github.com/docker/for-win/issues/12968

My workaround has been to start using GitHub codespaces for most dev stuff, it's worked quite nicely for the things I'm working on at the moment.
