Hello, frcgoncalves
Welcome to Microsoft Community.
Windows installed the update KB5032339 and WSL 2.0.9.0, and since then, I can not access WSL.
So far there haven't been any known issues in this update, as stated here:
Also, based on the official description, this update is mainly related to .NET Framework, but WSL doesn't need to use .NET Framework unless you're doing .NET development within WSL. So, in my opinion, this update shouldn't affect WSL. Of course, if you're not sure, you can uninstall this update and see if it makes a difference, then you can confirm whether or not this update is causing the problem.
I searched everywhere; it seems that I am not the only one with this problem.
I couldn't find a similar question in Microsoft Community, at least not recently in the English community. Maybe you saw similar problems out of Microsoft? Anyway, if you can't solve the problem, I suggest giving feedback on GitHub, where there is an official channel for feedback.

Microsoft Community isn't the best place for discussing WSL-related issues, and WSL developers don't usually pay attention to questions in Microsoft Community.
