I'm planning to get some more membership accounts, but the Lighthouse website isn't working, so I'm planning to set up multiple Epic clients. The current game logic is as follows:

Webpage binds the Epic account, and after entering the game, Epic will read the wallet configuration from the server, so once you've linked your Epic account, you only need to operate Epic to play the game.
I spent a long time today and found that backing up the configuration doesn't allow for multiple instances.
Here's the solution shared by AI for everyone.
Run multiple Windows instances; Windows user accounts isolate user environments, but the configuration process can be quite troublesome.
I'll look for other ideas.
