the log says that you are missing the system font and the banned word list.
you musta had them in the user folder in your previous citra directory and forgot to copy them over. When you have a folder named “user” in the same directory as the citra-qt.exe it will load the config and other save games from that folder. In essence, citra will run in portable mode with all the files inside that folder. Since you downloaded a new version, it checked for the user folder, didn’t find it, and created and new config in the permanent location
C:\USERNAME\AppData\Roaming\Citra which does not have the system font or the banned words list (and your save games!)
There are two options. You can copy the user folder from the old citra build to the new one (and always copy the folder every time you update!) or you can copy the contents of the user folder to
C:\USERNAME\AppData\Roaming\Citra\ After you do that, every build you download from there on out will use the config located there.
