Minecraft Launcher doesn't fully quit when playing snapshots on a Mac with the M1 chip

I play Minecraft on a MacBook Air with the M1 chip. Everything has been running great on the new hardware (thank you!), until I upgraded the OS to macOS 11.2.3 (Build 20D91).

When I quit Minecraft while playing a snapshot (the latest is 21w14a), it seems to quit, but Minecraft Launcher hangs and doesn't fully quit. When I click to launch Minecraft again, nothing happens. However, if I open Activity Monitor, I can see that the Minecraft Launcher process is stuck.

The solution is to use Activity Monitor to Quit (or Force Quit) Minecraft Launcher, and then I can launch Minecraft again.

This doesn't happen when I play 1.16.5 on the same MBAir; only when I play a snapshot.
