Player safety warning always reappears when launching an installation after changing the version, even if that warning has been disabled for that installation

To reproduce

1. Create an installation with an old version X
2. Launch that version
   → You get the player safety warning
3. Check the check mark so that you no longer get the warning for that installation
4. Close Minecraft
5. Change the version of that installation to another old version Y
6. Launch that version
   → You get the player safety warning again

("old version" = before 1.16.4)
