hi,
would you like kindly help check what is the I2C address when both A0 and A1 pins of INA231 are floatingbecause of customer's schematic error?

Section 8.5.5.1.1 of the datasheet says that "the state of pins A0 and A1 is sampled on every bus communication", so the resulting address is random, and might change at any time.
Floating CMOS inputs also increase power usage and might prevent the device from working at all; see [FAQ] How does a slow or floating input affect a CMOS device?
Clemens is correct, there is no way to know the address and it could randomly change.
