Hi @alexmegsur-maker,

Thanks for reporting this! The MiniflareError [ERR_RUNTIME_FAILURE] you're experiencing is a known Windows compatibility issue with Miniflare on Shopify Hydrogen projects.

Quick Fixes (in order):

1. Install/Update Visual C++ Redistributables (Most Common Fix)

Miniflare requires proper system libraries on Windows. Download and install both versions:

• https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist
• Install x86 AND x64 versions
• Restart your computer
• Try npm run dev again

2. Clean Reinstall Dependencies

rmdir /s /q node_modules
del package-lock.json
npm cache clean --force
npm install
npm run dev

3. Run Terminal as Administrator

Sometimes Miniflare needs elevated permissions for file access on Windows. Right-click your terminal and select "Run as administrator."

4. Move Project Closer to Root

Windows MAX_PATH limitations can affect nested node_modules. Try moving your project to a simpler path (e.g., C:\hydrogen-project instead of C:\Users\...\Desktop\...).

5. Use WSL2 (Most Reliable Long-term Solution)

If the above don't work, WSL2 eliminates these Windows-specific issues entirely:

wsl --install
# Then in Ubuntu:
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt-get install -y nodejs libatomic1

Additional Info Needed

To help further, can you provide:

• Your Node.js version: node --version
• Your npm version: npm --version
• Your project's package.json (specifically Hydrogen/Weaverse versions)

Please try these solutions in order and let us know which one resolves the issue! 🙌
