404 For Current Project - Work Lost

Describe the bug
Working on a project I then attempted to push it to the github repo by pushing the github button at the bottom of the screen (luckily I've only lost 30 minutes worth of work, but still demoralizing).

To Reproduce
Steps to reproduce the behavior:

1. Spend time making a game in the web editor
2. Attempt to push to github
3. Notice that the screen goes white, 404 errors on your CDN version of the app
4. Cry a little bit

Expected behavior
The game should continue to work and load from the CDN as much as it did earlier today.

Desktop (please complete the following information):

• OS: Mac
• Browser Chrome
• Version 149.0.7827.114

Smartphone (please complete the following information):

• Device: [e.g. iPhone6]
• OS: [e.g. iOS8.1]
• Browser [e.g. stock browser, safari]
• Version [e.g. 22]

Additional context
Incognito has the same error, other games load fine.

CURL that's returning the 404:

curl 'https://cdn.makecode.com/api/gh/kikketer/battleturf?cdn=20260712' \
  -H 'sec-ch-ua-platform: "macOS"' \
  -H 'Referer: https://arcade.makecode.com/' \
  -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/149.0.0.0 Safari/537.36' \
  -H 'sec-ch-ua: "Google Chrome";v="149", "Chromium";v="149", "Not)A;Brand";v="24"' \
  -H 'DNT: 1' \
  -H 'sec-ch-ua-mobile: ?0'

I have noticed that there's no CDN call like this for the working games, not sure why this one has this whole CDN call.

Visual Studio Code + Git is great for a backup but the asset management can be a little flakey in that scenario, that's why I flip between the two (MakeCode web for assets, VS for code and testing)

Start by reproducing the failure in the MakeCode web editor: use the GitHub button, then compare the failing CDN request for the project with requests for working games. Investigate the CDN/API path shown in the issue and verify that pushing a project no longer leads to a white screen or 404, while the game continues to load.
