Error when modifying partition table in ESP32

Hi, I am trying to modify the partition table of my ESP32. Specifically to expand the size of the nvs partition and reduce the size of the SPIFFs partition. The code gets uploaded but the ESP throws this error while booting:

This is my partition table:

# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  500k,
otadata,  data, ota,     ,8k,
app0,     app,  ota_0,   , 1M,
app1,     app,  ota_1,   ,1M,
spiffs,   data, spiffs,  ,500k,

Not sure why this is happening.

Seems like it’s just reading erased flash values (0xffff....) and not the program. Maybe PIO doesn’t upload the application binaries into the correct address in flash. When invoking a “Verbose Upload” (pio run -t upload -v), what is the esptool.py invocation and which file is uploaded to which address?

Also, with what full platformio.ini and other files can the problem be reproduced?

Thanks for the quick reply. Not sure if this is what you asked for:
