Running the bevy breakout example in WSL

I am trying to run the bevy breakout example on a Windows PC with Ubuntu inside a WSL shell. I followed the bevy quick start guide. But I get this error:

Command:

cargo run --example breakout

Message:

    Finished dev [unoptimized + debuginfo] target(s) in 0.09s
     Running `/home/JohnDoe/bevy_example/bevy/target/debug/examples/breakout`

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

It looks like the display is not configured right. How do I do that?

The output of

wsl -l -v

is

    Side note - you can upgrade to the latest WSL version by installing from the Microsoft Store, but I don't think that's going to resolve the issue (yet it may) - NotTheDr01ds

    Installing the new WSL from the Microsoft Store did fix the problem! Thank you!
