Live preview in brackets fails after the latest Chrome update (Version 111). You will get the following error:

The fix:

A new release of Brackets with the fix will be available by 15'th march. Please follow this issue to track.

Till we release the update, you can fix the issue by one of the two methods:

Method 1: Use phcode.dev - the browser version of Brackets.

Phoenix brings all the powers of Brackets and its Extensions to web browsers; no install needed.
Click here to open phcode.dev . New native builds of phcode and Brackets are in the works and will be available by June-July.

Method 2: Enable Experimental live preview in Brackets

1. open file menu > Enable Experimental Live Preview
2. Live preview should now work in brackets.

Note that experimental live preview does not work with custom preview servers in project settings
