backup does not work on first boot

[Blastmun]

I don't know if I would have an answer, but my assembly worked perfectly for 12 months, except that my esp card became HS. So I wanted to reinstall this project on a wemos d1 mini clone, everything goes well but when I connect to the wifi access point, I modify the parameters and if I click on save it restarts esp without taking into account my modifications. On the other hand, if I modify the buttons, there the configuration is taken into account. Here are the logs during the save

Did you change the platform parameters the Arduino IDE for the D1 mini before uploading the firmware? Did you initialise the SPIFF with the SPIFFS tool? Have you tried to repeat the whole process? Maybe something went wrong the first time.

Avez-vous modifié les paramètres de la plate-forme de l'IDE Arduino pour le mini D1 avant de télécharger le firmware? Avez-vous initialisé le SPIFF avec l'outil SPIFFS? Avez-vous essayé de répéter tout le processus? Peut-être que quelque chose a mal tourné la première fois.
I proceed as in the YouTube video, I just modified the file because Arduino 1.8.19 gives me errors.

C:\xxx\Jarolift_MQTT\Jarolift_MQTT.ino: In function 'int keeloq()':
C:\xxxx\Jarolift_MQTT\Jarolift_MQTT.ino:454:1: error: no return statement in function returning non-void [-Werror=return-type]
454 | } // int keeloq
| ^
similarly for:
480 | } // int keygen
642 | } // int rx_keygen
655 | } // int rx_decoder
so I replace int with void

and it's OK.
