HELP marlin-2.1.2.2-mpx.3 Thermal Runaway HELP

Since I'm such a noob at this, maybe I'm asking the wrong question. Is there something in my config that would cause or allow an incorrect thermal runaway error?
I can't see to get this to be stable. It doesn't matter the size of the print it prints about 4-6 layers then the fast beep, thermal runaway message for the extruder and the firmware resets. This is driving me bonkers.

Oh yeah, heres my hardware config.
I am running an old Hictop i3 clone with an MPX.3 controller. I successfully flashed it to Marlin using marlin-2.1.2.2-mpx.3-bltouch-main, However, I do not have a bltouch so I disabled that in the sketch. Now when I try to print it goes like normal for about 3 layers then I get a series of Beeps and it resets. In my terminal it reports an error: Thermal Runaway for the extruder0. I do not have multiple temp sensors, I followed this [github.com] for a thermal runaway bug. Nothing seems to help. I'm pulling my hair out. I'm attaching my sketches, any help would be appreciated.

You have enabled MPCTEMP but you dont seem to have updated any any the following to match your hardware.

#define MPC_HEATER_POWER { 40.0f }                  // (W) Heat cartridge powers.

  #define MPC_INCLUDE_FAN                             // Model the fan speed?

  // Measured physical constants from M306
  #define MPC_BLOCK_HEAT_CAPACITY { 16.86 }           // (J/K) Heat block heat capacities.
  #define MPC_SENSOR_RESPONSIVENESS { 0.0755 }         // (K/s per ∆K) Rate of change of sensor temperature from heat block.
  #define MPC_AMBIENT_XFER_COEFF { 0.0534 }           // (W/K) Heat transfer coefficients from heat block to room air with fan off.

use M306 [marlinfw.org]

My Bad, I ran M306 T and added the settings using the M500 command, but I didn't add it to the Config.h maybe it lost them. I'm going to add them and run a test.
Thank you!

Here is my section of the MCPTemp from M306 T

// Measured physical constants from M306
#define MPC_BLOCK_HEAT_CAPACITY { 16.45 } // (J/K) Heat block heat capacities.
#define MPC_SENSOR_RESPONSIVENESS { 0.0745 } // (K/s per ∆K) Rate of change of sensor temperature from heat block.
#define MPC_AMBIENT_XFER_COEFF { 0.0722 } // (W/K) Heat transfer coefficients from heat block to room air with fan off.
#if ENABLED(MPC_INCLUDE_FAN)
#define MPC_AMBIENT_XFER_COEFF_FAN255 { 0.1589 } // (W/K) Heat transfer coefficients from heat block to room air with fan on full.
#endif
Didn't help!
Still getting the error.

Found the below in the Configuration_adv.h
Maybe this will help someone else.
The default was 40 sec and 4 degrees.



If you get false positives for "Thermal Runaway", increase
* THERMAL_PROTECTION_HYSTERESIS and/or THERMAL_PROTECTION_PERIOD
*/
#if ENABLED(THERMAL_PROTECTION_HOTENDS)
#define THERMAL_PROTECTION_PERIOD 60 // (seconds)
#define THERMAL_PROTECTION_HYSTERESIS 6 // (°C)
