My Switch crashes on boot after I installed a font

• Cause 1: You installed a font that was too large in file size (maximum file size being 1.9MB). You can remove your installed custom font data by navigating to sd:/atmosphere/contents and deleting the 0100000000000811 folder.
• Cause 2: You installed a font that wasn’t the right file type (e.g. .otf). You can remove your installed custom font data by navigating to sd:/atmosphere/contents and deleting the 0100000000000811 folder.

Note: contents is called titles on Atmosphère version 0.9.4 and below.
