Launchbox on Windows 11 crashes when importing games from Epic

[Giuseppe Pinto]

Launchbox 12.14 worked fine on Windows 10. I recently upgraded to Windows 11 and since then I get the following error when trying to use the Import Epic Games Wizard.

Epic Games recently changed their backend authentication code, breaking logins for all programs. We have a fix in place in the current LaunchBox beta, which you can update to from within LaunchBox if you would like to take advantage of it before it hits the official release channel.
