🛠️ Android Emulator Crash FIX — `StartService FAILED with error 4294967201`

❗ Problem

When launching the Android Emulator, I kept getting this vague and frustrating error:

Running Android Emulator hypervisor driver installer
[SC] StartService FAILED with error 4294967201
The emulator process for AVD  has terminated.

Problem:

While building ESP32 projects on ARM64 (e.g., Raspberry Pi, Termux), PlatformIO shows this error:

xtensa-esp32-elf-g++: not found [Error 127]

Solution:

1. Download ARM64 toolchain:

This guide covers installing Deno.js and Bun.js in Termux using proot Ubuntu.

1. Install Termux and Proot Ubuntu

First, update Termux and install Ubuntu using proot-distro:

pkg update && pkg upgrade -y
pkg install proot-distro -y
proot-distro install ubuntu
proot-distro login ubuntu

	#!/bin/bash
	# Configure GRUB for serial console in Debian (Termux-friendly)

	GRUB_FILE="/etc/default/grub"
	BACKUP_FILE="/etc/default/grub.bak.$(date +%F-%T)"

	echo "🔹 Backing up current GRUB config to $BACKUP_FILE"
	sudo cp "$GRUB_FILE" "$BACKUP_FILE"

	echo "🔹 Configuring GRUB for serial console..."

	async function getFinalUrl(inputUrl) {

	if (!idMatch) {
	throw new Error("Invalid URL format, can't extract ID");

	const id = idMatch[1];
