Same error. Claude 2.1.136 not usable in VScode. Switching to 2.1.133 fixes it.

yeah. Just downgrade to 128 and uncheck auto update

I actually do not see an option to downgrade/roll back...?

You can download the specific version of the extension from the drop down menu and then in a shell run the following: code --install-extension <PATH_TO_VSIX> --force

If you're in vs code just go to the extension and click the arrow next to uninstall and you'll see Install Specific Version
