I can't run anything

Anything just either crash or freeze. No in between. Pokemon Let’s Go Pikachu boots but only up until the gamefreaks intro, and then crashes. NSMBU Deluxe used to run until the title screen, and freezes after that, but after a couple of updates I can’t even get to the intro screen.

And then I tried to run something that has perfect compatibility, that is Harvest Moon. Crashes.

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.

set your pagefile to at least 20GB if you have 16GB RAM. More if you have 8GB.

If you still have the issue then post a log after that.
