Lost SPIFFS data

[galzoltan42]

Hello Everyone! My problem is that the ESP32 Wroom 32 does not retain the data stored in SPIFFS. I simply upload spiffs.bin via OTA (AsyncElegantOTA), which contains a total of 48KB of data, (12 .png images) and display this on a TFT display. There is no other data in SPIFFS. Everything works fine, but e.g. after a power failure, the data stored in SPIFFS disappears. Images are not displayed on the TFT display. In such cases, I always upload the spiffs.bin file via OTA, then it works. (spiffs.bin: 128kb)
Board setting: Minimal SPIFFS (1.9MB APP with OTA/190KB SPIFFS), Erase all flash before sketch upload : Disabled
Setup:
if(!SPIFFS.begin(true)){ return; }

loop:
.... setPngPosition(117, 0); load_file(SPIFFS, "/Borult_030.png");

What could be the problem?
