I looked into the FastLED SmartMatrix controller, and it was written for back when SmartMatrix Library could only support a 32x32 panel (I think). When using the controller, the SmartMatrix configuration part of the sketch is encapsulated inside FastLED. Configuration is a lot more complicated now, so I’m not sure how to pass all the parameters into FastLED to be used by the controller, and it seems like a lot of work to figure it out.
Compare this:
// uncomment one line to select your MatrixHardware configuration - configuration header needs to be included before <SmartMatrix3.h>
//#include <MatrixHardware_Teensy3_ShieldV4.h> // SmartLED Shield for Teensy 3 (V4)
//#include <MatrixHardware_Teensy4_ShieldV5.h> // SmartLED Shield for Teensy 4 (V5)
//#include <MatrixHardware_Teensy3_ShieldV1toV3.h> // SmartMatrix Shield for Teensy 3 V1-V3
//#include <MatrixHardware_Teensy4_ShieldV4Adapter.h> // Teensy 4 Adapter attached to SmartLED Shield for Teensy 3 (V4)
//#include <MatrixHardware_ESP32_V0.h> // This file contains multiple ESP32 hardware configurations, edit the file to define GPIOPINOUT (or add #define GPIOPINOUT with a hardcoded number before this #include)
//#include "MatrixHardware_Custom.h" // Copy an existing MatrixHardware file to your Sketch directory, rename, customize, and you can include it like this
#include <SmartMatrix3.h>
#include <FastLED.h>
#define COLOR_DEPTH 24 // This sketch and FastLED uses type `rgb24` directly, COLOR_DEPTH must be 24
const uint16_t kMatrixWidth = 32; // known working: 32, 64, 96, 128, 256
const uint16_t kMatrixHeight = 32; // known working: 16, 32, 48, 64, 128
const uint8_t kRefreshDepth = 36; // known working: 24, 36, 48 (on Teensy 4.x: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48)
const uint8_t kDmaBufferRows = 4; // known working: 2-4, use 2 to save memory, more to keep from dropping frames and automatically lowering refresh rate
const uint8_t kPanelType = SMARTMATRIX_HUB75_32ROW_MOD16SCAN; // use SMARTMATRIX_HUB75_16ROW_MOD8SCAN for common 16x32 panels
const uint32_t kMatrixOptions = (SMARTMATRIX_OPTIONS_NONE); // see http://docs.pixelmatix.com/SmartMatrix for options
const uint8_t kBackgroundLayerOptions = (SM_BACKGROUND_OPTIONS_NONE);
const uint8_t kScrollingLayerOptions = (SM_SCROLLING_OPTIONS_NONE);
SMARTMATRIX_ALLOCATE_BUFFERS(matrix, kMatrixWidth, kMatrixHeight, kRefreshDepth, kDmaBufferRows, kPanelType, kMatrixOptions);
SMARTMATRIX_ALLOCATE_BACKGROUND_LAYER(backgroundLayer, kMatrixWidth, kMatrixHeight, COLOR_DEPTH, kBackgroundLayerOptions);
SMARTMATRIX_ALLOCATE_SCROLLING_LAYER(scrollingLayer, kMatrixWidth, kMatrixHeight, COLOR_DEPTH, kScrollingLayerOptions);
void setup() {
// uncomment the following lines if you want to see FPS count information
// Serial.println("resetting!");
Serial.begin(115200);
delay(3000);
matrix.addLayer(&backgroundLayer);
matrix.addLayer(&scrollingLayer);
matrix.begin();

Sorry, but I’m not going to try to get the FastLED SmartMatrix controller working again.
