I have noticed something similar on Windows 11 and it's quite maddening. I did not notice this when I was still running Windows 10. My CPU usage skyrockets after I try to 'resume' from a sleep, and my WSLg terminal emulator (guake) becomes frozen and unresponsive. Running wsl --shutdown from a new terminal hangs forever.

This is what my CPU usage due to WSL looks like during this event; my laptop fan hates it and the bottom of my laptop burns!!:

I experience this frequently after a long laptop 'sleep'.

Having the same issue here!

Same/similar issues, all related to sleep mode while a WSL2 is running (Win11, Ubuntu 20.04, Dell XPS 15 9520).

wsl freezes after even a short sleep. Hibernation works. XPS 15 9520. W11.
have to do settings/installed apps/wsl -> advanced -> reset
after that it works.
I'm using docker desktop which freezes too as it is built on top of wsl.

I am seeing a somewhat tangential issue, but I think it may help triage the issue.

When you see the issue, are you using Windows Terminal or some other command-line terminal?

In my case, it is Windows Terminal (Preview) that is causing the hang/fan to spin up. It also causes my external mouse (which has a driver, and has special mouse bindings for WT) to stop working, while inside of WT. Once I move the mouse outside of WT, it 'wakes up.'

I normally use WT for both PowerShell 7 (7.3) and WSL (Debian and/or Oracle Linux.

I also use WT for Cygwin64 and Git-bash.

I was using WT, but definitely not preview (v1.16.10262.0).

I've switched my computer to Linux since, no more problems!

If you want to keep your data, 'Reset' is not working. It will erase your data definitely.

Crashes after wake from sleep. Hibernation does not work for me. (Windows 11 Pro, i7, 40GB RAM, 2023-10 Cumulative Update (KB5031358)) Task Manager shows 12 processes for WSL, and over 100 instances of conhost.exe running, I assume it's each time VS Code tries to reconnect:
