Try setting up a portable Citra build and run just your game, don’t install your update:
Go to Download Citra - Citra and select Manual download. Then under Nightly Build, click on your operating system’s icon to the right of the latest build available to download the build.
Extract it (.7z can be extracted using Winrar or 7zip) (.tar.gz can be extracted natively on MacOS) and put it where ever you wish. Inside the extracted mingw folder, create a folder called user. This Citra should now store all of its config, save files and such inside of this user folder.
Check to make sure that this user folder is in the same folder that contains citra-qt(.exe)
Now run the citra-qt executable found inside of the mingw folder and run your game.
