Unexpected token } in JSON at position

[JarnDev]

Environment data

• VS Code version: 1.33.1
• Extension version (available under the Extensions sidebar): 2019.4.11881
• OS and version: Win 10
• Python version : 3.6.6
• Type of virtual environment used: virtualenv
• Relevant/affected Python packages and their versions: pylint

Expected behaviour

Extension Activates, and work normally with codes and pylint
python: select Interpreter works

Actual behaviour

Activation of extension Fail, and nothing related with python works.
python: select Interpreter pops an error "command 'python.setInterpreter' not found"

Steps to reproduce:

I was working normally, then the lint stopped. When I tried to fix the problem I realized that the python extension was broken.
Probably the last commit, because the problem seems to be inside the extension's JSON as shown on console error.

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)
