Hi,
I’m unable to edit the code in any of my theme files. When I click “Edit code,” it opens the editor screen but stays stuck on “Loading Editor” indefinitely.
I’ve tried logging in through incognito mode, using different computers, and different browsers (Chrome, Safari, and Edge), but nothing seems to work.
I’d really appreciate your help in resolving this issue.
There’s also trying on a different browser, device, or clearing the cache.
If the issue continues advanced users probably should investiage using the shopify-cli, or themekit to work on theme code locally in desktop software.
Then contact shopify support advisors directly to complain about the new editor problems.

Though this is just the sad state of affairs you can probably come to expect after they decided to force a full blown bloated IDE on merchants that’s 3x the size and 3x slower than the old reliable editor; if it even works.
Imagine making everyone use a jackhammer when they just need a hammer, then the jackhammer keeps breaking.
Check shopifystatus.com first for platform issues. If clear, temporarily disable recently installed apps in your Shopify admin as they can conflict with the editor. If the problem continues, contact Shopify Support directly as it may be an account-specific issue requiring their investigation.
