spawn issue occurs on Windows 32 bit, but works with Win64 bit.

}

My code is here:

import ffmpeg from "fluent-ffmpeg";
const ffmpegPath = require("ffmpeg-static").replace(
  "app.asar",
  "app.asar.unpacked"
);
const ffprobePath = require("ffprobe-static").path.replace(
  "app.asar",
  "app.asar.unpacked"
);

ffmpeg.setFfmpegPath(ffmpegPath);
ffmpeg.setFfprobePath(ffprobePath);

function startTranscode(input, output) {
    //error throws when this function called in win 32
      ffmpeg(inputPath)
        .format(format)
        .on("start", () => {
          console.log("conversion:start", inputPath, outputPath);
        })
        .on("progress", (data) => {
          console.log("conversion:progress", data, data.percent / 100);
        })
        .on("end", (e) => {
          console.log("conversion:end", inputPath, outputPath, e);
        })
        .on("error", (e) => {
          console.error("conversion:error", e);
        })
        .save(outputPath);
 }

in electron build configuration:

externals: ["fluent-ffmpeg", "ffmpeg-static", "ffprobe-static", ],
chainWebpackMainProcess: (config) => {
        config.plugin("define").tap((args) => {
          args[0]["process.env.FLUENTFFMPEG_COV"] = false;
          return args;
        });
      },

Any idea?
