This worked, thanks! Am I supposed to stay on the `floxmain` branch or should I go back to the `x86_64-darwin.default` branch I was on?

Awesome! You can just leave it on `floxmain`

The fix just rolled out to `stable.flox.flox-prerelease`. Thanks for finding that for us!

Thanks Matthew. I was able to upgrade to the prerelease version (r111) but I am actually not sure how I did it :-). I think I `flox pull -e flox/prerelease` and reactivated the environment, at first it didn’t work and eventually it did (maybe I did a `hash -r` in the meantime).

Now the conversion of both my `default` and my `flox/prerelease` environments worked ok and I can also edit them and see the nix format for the environment. I was even able to reintroduce my previous alias :-).

About upgrading flox. I now did

```auto
flox list -e default

```

Removed my current flox version in `default` (it was r93), listed as 2 in the list:

```auto
flox rm 2 -e default

```

and installed the prerelease version with

```auto
flox install stable.flox.flox-prerelease -e default

```
