I opened developer tools and saw what's wrong.
There was error message:

ERR Unexpected token < in JSON at position 0: SyntaxError: Unexpected token < in JSON at position 0
    at JSON.parse (<anonymous>)
    at Object.t.asJson (file:///C:/Users/2/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/workbench/workbench.desktop.main.js:1714:949)

I followed it, it was getExperiments, 178 line at experimentService.ts.

return asJson(context).then(..)

Inside asJson(context), buffer.toString() returns next weird text:

I double checked network tab and there was request to https://az764295.vo.msecnd.net/experiments/vscode-experiments.json, and response same as above.

But when I send request directly to same url, it's response is pretty normal:

Even I copy all as cURL it looks very normal.

I checked other svg requests but none of them matched. Absolutely nonsense.

Response of request said about WSL extension, so I turned it off even deleted it but same error still occurres.

So I just changed workbench.enableExperiments to false, to just skip function, and it totally works very well.
After few Error querying extensinos gallery canceled messages, I'm finally able to search on Marketplace.

I have no idea about that request, and it seems like I was not only for me (#81814).

After disable experiments, I reinstalled extensions and searches are just working very fine, no problem at all.

@20chan Thanks for figuring this out. I was completely clueless from where this is coming. Now I know because of your investigation.

@roblourens I remember you are chiming in for some experiments related issues. So assigning to you,

[20chan]

I found what was that 'svg-like' texts are. It was file:///..../AppData/Local/Programs/Microsoft%20VS%20Code/resources/app/extensions/git/resources/icons/dark/open-change.svg and it was very weird because it's in my disk.

Look at captured image in my issue, network tab in developer tools.
Status code of request to vscode-experiments.json is 200 (from disk cache), and I think that from disk cache is the problem.

For test, I set workbench.enableExperiments to true and re-generate issue, and checked Disable cache on network tab of developer tools. Response was very fine, also after enable cache and refresh code.

But now I can't reproduce issue again lol

[roblourens]

Can you check whether this works in Insiders? I might have fixed the same issue there.

[20chan]

@roblourens I'm sorry but as I mentioned, I can't reproduce this issue anymore.

[roblourens]

Are you using a proxy or vpn? I'm not sure why you getting that svg, but in any case, I looked at a similar issue earlier this month and fixed it so that if that request fails, it will not fail the whole marketplace search.
