Information about your environment

• OS version: sys 11.13.0-45U
• PKSM version: 9.0.1
• Entrypoint: i dont know what does it mean :(

Additional context
before this i had another inferior version of pksm, y wanted to update it to 9.0.1, so i instaled the new cia, already having the old one instaled, so i deleted it from the 3ds folder, and the fbi title list. wen I instaled the new pksm it doesnt worked. i also tried with a 3dsx file instead of a cia but everything still the same.

Try backing up and immediately restoring your PKSM ExtData with Checkpoint 3.7.4 (YES, the version matters.) If that doesn't work, please join our Discord server for more help.
