Launcher is no longer launching snapshots despite them being selected under "Installations

The launcher is no longer allowing me to launch the game with 1.17 snapshots. I triple-checked that "Snapshots" is checked under "Installations", and I am selecting "Latest Snapshot" before loading the game, but it's stuck at 1.16.5. I had a friend open his launcher and he said the same thing happened to him, so odds are it's a launcher bug rather than an error on my end.
