These two issues are both about loopback connection.

Newer versions of minecraft require java16+ Those minecraft versions that support java 11 do not have this issue if you use java 11 to run them

Those minecraft versions that support java 11 do not have this issue if you use java 11 to run them

But older minecraft versions such as 1.16.5 also have this issue if you run them on java 16+

Adding to this. Gave the program access to %appdata%. Get the error message "failed to open a new selector" when trying to play minecraft online or world. According to the internet the issue means it can't reach some files. Also it takes 4 minutes just to launch the launcher.

please try adding

OpenFilePath=*\Temp\socket_*

to the sandbox and let me know if it fixed the issue

it worked for me. Thank you so much!

And its getting better with the next build you will no longer need that workaround, I'm adding propper support for this: https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ that is what caused the issue.

Hello David, I wanted to start using sandboxie plus again.

But I launch minecraft, it shows running in the sandboxie list. But then the screen doesn't pop-up.

I revisited this issue, but that temporary fix doesn't work.

for some reason the issue is that it just takes incredibly long to startup.

I ran it to give it another try. Forgot about it and ~30 minutes later the screen popped up.

Another issue is required for it.
