I had the same problem;
Go to 'c:\Users\hp\.vscode\extensions\extensions.json' on your computer and rename the extensions.json file you can add an extra s to make it extensionss.json. Then go back to vscode and install the extension of your choice, a new extensions.json file will be created.
You can go ahead and delete the extensionss.json file.
All the best!

Hello @Rishant Jayaswal ,
Welcome to Microsoft Q&A forum.
The error message indicates that operation not permitted, perhaps it’s blocked by permission limitation. Please find the file(s) that mentioned in error message, right-click the file, select Properties, switch to Security tab, select the corresponding user, click Edit…, confirm that the account has been assigned the proper permissions.
Try to reboot your machine and directly open VS Code and install the extension(in case the file is locked by other program/process).
Besides, is there any permission limitation on your machine? Are you using any antivirus software/extension/proxy? If so, please try to disable them temporarily and test again.
Best Regards,
Tianyu

I don't know how this happened, but I ran into the same issue. I just checked the output of Log (Shared) in the vs code terminal, and I saw the following:

soo... then I deleted that folder:
sudo rm -rf /Users/sgtpooki/.vscode/extensions/myxvisual.vscode-ts-uml-1.0.4
Then I tried installing the extension again and it worked.

I have no idea how I got into this state, but I did, and out of all of the similar issues found online, no one else seems to have run into this particular version, but hopefully this helps you solve your issue.
At the very least, check the output tab in the vs code terminal, and toggle the different terminals in the top right:

r/vscode on Reddit: I cannot install any extensions.
December 29, 2023 - I also tried the vscode.dev and it worked fine for my end. I was even able to install the Python extension on that. Sometimes, but most of the time I have stable internet speeds. (20-50 mbps) Idk how to check ping properly, but I found this website LOL Ping Test and mine is 250 for the NA servers. I got the VSIX that I manually downloaded from this site and yes I can still access it.

I was able to install some extensions after my network admin disabled SSL Inspection on my machine.
This is not ideal as I wouldn't want this turned off for everything.
After re-enabling inspection, I set my User Settings to
"http.proxyStrictSSL": true
I am still unable to download packages, but this does appear to be the problem.
