Stuck at "Sync: Reading Settings and Extensions", consuming 100% CPU

[borekb]

🐛 Describe the bug

When I run Sync: Update/Upload Settings, the process is stuck at "Sync: Reading Settings and Extensions" and the Code Helper process is consuming 100% CPU until I restart VSCode.

I think it started happening after I update to VSCode 1.39 but I might be wrong.

🌴 Visual Studio Code Version : 1.39.2
🌴 Code Settings Sync Version : 3.4.3
🌴 Standard or Insiders : standard
🌴 Portable or Installed : installed
🌴 OSS or Official Build : official
🌴 Operating System : macOS Catalina
🌴 Occurs On: Upload
🌴 Proxy Enabled: No
🌴 Gist Id: n/a

Have you tried

1. removing the extension,
2. deleting the folder of extension (if code in any case doesnt remove it)
3. installing and resetting the extension settings
4. Restarting the code

Kindly let me know about the status, or i'm closing this issue assuming its fixed.

@shanalikhan Sorry, just got to it. Unfortunately, the problem persists. I followed your steps but when passing OAuth on GitHub, I end up on this strange screen:

There should probably be a list of Gists but I see nothing. BTW this is my settings Gist:

https://gist.github.com/borekb/da094142cab10f5f40ad024da92bf692

Back on the "Welcome to Settings Sync" screen, there's a link called "Download Public Gist" which I followed. However, it ended up in an error:

In dev tools console, there were two errors:

That "JSON" above is probably some inbetween step as I don't have comment-less keybindings.json neitner on my computer, neither in Gist (see here).

I suspect the trailing comma in keybindings.json may have something to do with it but this was working fine before.

[borekb]

Sorry, I sent the comment before fully finishing it, it's now updated with all the info.

[borekb]

(I only see the error on download; upload doesn't produce any errors, just gets stuck and uses 100% CPU until I restart VSCode.)

I have a similar issue and found this in the console:

I've tried to manually remove trailing commas from my JSON in the Gist but it didn't help:

I haven't yet found a workaround that would allow me continue using this extension.

@borekb @arnauldvm

I will hopefully share a custom build fixing this issue in this week with you guys before releasing it to public.

[filmico]

Guys, I´m experiencing this same issue with win 7/win10. IT was working great and suddenly I cannot sync anymore in new installations.
Just for testing, I reset the extension in a computer that all was working and syncing and clean the gist on git hub to start over again and the same problem start to happen in this station were all was working fine. Any idea on how to fix it? what are the files we can edit and check for extra comma in the json config file?

[borekb]

@shanalikhan do you have a build that we could test already? Thanks.
