SSBU not loading after installing 12.0.0 update and DLCs

The game just don’t open. It is stuck at the launching screen with the blue and orange bar forever scrolling. Before installing the update, the game opens but after the installation, the game just won’t open anymore.

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

Try to boot the game and post me that log file: Getting Log Files - yuzu

Done. The game still doesn’t open but here is the log file.

You lack RAM, yuzu requires a minimum of 8GB, and a minimum of 12GB if you use an integrated GPU.

Then how am I able to play before intalling the update?

Lower requirements by the game, you added a lot of thins with the update.
Try with multicore disabled, or async GPU disabled, that can reduce RAM use. But we don’t plan to support less memory than the Switch has, 8GB is the minimum.
