AFE4404: Receiving a NACK when trying to communicate

I am using a PSoC 4200 to communicate with the AFE4404. When I try to read or write to it, I receive a NACK from the AFE4404. Below is my read and write code and the waveform that is sent over I2C when I am trying to write to registers.

Other Notes

- I have tested the code below on other sensors and it works just fine. 

- The PCB I am using was designed by someone else and I cannot toggle the RESETZ pin 

- I also cannot measure voltages from RESETZ, TX2, INM, and INP

int PulseOx_Read(uint8 reg)
{
    uint8 Write_Buf[1] = {0};
    Write_Buf[0] = reg;
    
    uint8 Read_Buf[3]={0};
    int readVal;
    
    DataBus_I2CMasterWriteBuf(AFE_SLAVE_ADDRESS, (uint8 *)Write_Buf, 1, DataBus_I2C_MODE_NO_STOP);
    while((DataBus_I2CMasterStatus() & DataBus_I2C_MSTAT_WR_CMPLT)==0){}

    DataBus_I2CMasterReadBuf(AFE_SLAVE_ADDRESS, (uint8 *)Read_Buf, 3, DataBus_I2C_MODE_REPEAT_START);
    while((DataBus_I2CMasterStatus() & DataBus_I2C_MSTAT_RD_CMPLT)==0){}
    
    readVal = Read_Buf[0];
    readVal = (readVal << 8) | Read_Buf[1];
    readVal = (readVal << 8) | Read_Buf[2];
    
    if (reg >= 0x2A && reg <= 0x2F)
    {
        if(readVal & 0x00200000)
        {
            readVal = ~readVal + 1;
            readVal &= 0x003FFFFF;
            readVal *= -1;
        }
    }
    
    return readVal;
}
