SparkFun_ST25DV64KC library not working on platformio

I have this flashed code in my ATTiny814 which is connected to EEROM(ST25DV64KC), but I am unable to read any data from the NFC app on my phone.

Write operations are happening correctly; they can be verified by the data shown on the serial monitor when a read operation is performed.

I want to know if a special command is there to enable the RF interface on ST25DV64KC or if it is functional by default. Thanks

If there’s an issue with the library itself, please file an issue in https://github.com/sparkfun/SparkFun_ST25DV64KC_Arduino_Library/issues.

Or did you mean that it works correctly when using the Arduino IDE, but not PlatformIO?
