Comment:
Thanks, I remember replying on Discord that I could reproduce this.
Bisected to a060a22ee2dde7aa29a5a29120087c4864887325. Hey, that was me!
Looks like some debugging is needed around why
`apps.set_available_apps(cls.available_apps)` is not being called at a
point that works for the parallel test runner.
Would you like to look into this a little bit? I'm marking as a release
blocker, and since the alpha is scheduled to go out this week, I can make
some time to investigate as well. Having a couple people look at it will
be helpful.

RE: your original proposal, I think we have another option, which would be
to do this, but I think you're right this is just masking the deeper
issue:
