When pressing the "Open World Folder" button in the Edit World menu, the game successfully opens the folder, but the game freezes and cannot be recovered unless killed.

The game also doesn't minimise, like it normally would. Note that this also effects the "Open Backups Folder" button.

Steps to reproduce

1. Select a world in the Singleplayer menu
2. Click "Edit World" in the bottom toolbar
3. Select "Open World Folder"
   → The game freezes
4. Close the file manager window that has opened
   → The game is still frozen
5. Restart the window manager
   → The game recovers

Observed behaviour

The game freezes with the "Open World Folder" still in its hover state. Music stops shortly after.

Expected behaviour

The game would continue normally.

Notes

• I can consistently reproduce this on my machine, but I'm assuming that this is an OS-specific thing. I've added some (hopefully) relevant information to the Environment field.
• If the file manager is already open, the game does not freeze, but it does log an error:

• 1.17.1 and 21w38a both seem to not have this issue.
