When ever I try to open the new 1.23.12 launcher a error occurs.

Hi, Josh.

I will absolutely try my best to answer those questions for you!

Here is a screenshot to show my Windows version: Here.

The mod launcher is not pinned to the taskbar or the start menu.

About the save files, how would I run my save file from the 1.16.2 launcher, to the new 1.23.12 launcher?

Kind Regards,
King Nuke

Hi King,

Sorry for the delays in getting back to you on this, what do you mean by the save file not working between launchers?

Could you also upload the file if possible please?

Thanks,
Josh
