Description

Your Windows build number: (Type
verat a Windows Command Prompt)
19609 -
What you're doing and what's happening: (Copy&paste the full set of specific command-line steps necessary to reproduce the behavior, and their output. Include screen shots if that helps demonstrate the problem.)
Was browsing my Ubuntu WSL2 instance's filesystem using the new File Explorer WSL distro integration -
What's wrong / what should be happening instead:
Suddenly, File Explorer could no longer connect to the distro.

Then tried connecting to distro via Windows Terminal, but got:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
[process exited with code 4294967295]

Can no longer access my Ubuntu WSL distro at all.
