Code Complete not working after Mac Sequioa update

After installing verion 21.5 on a new Mac running Sequoia, the Code Hints or code completion does not work even with manual control-spacebar.   I  have the box checked to "Enable code hints" in Settings>Code HInts, and also tried linting changes.

I read the brackets.json file needs a specific line of code  "codehint.Hints":{

"javascript":true

}.  which it does not have, but I cannot edit the file as it's read only.

Earlier I had a notification appear about extensions available to edit, but I didn't insall any and it says "(no extentions availble)"  so not sure if that's part of it.

Not sure what to do or how to recreate the brackets file.
