Broken extension parser #1353

Environment data

• VS Code version: 1.36.1
• Extension version: 2019.6.24221
• OS and version: Windows 10 Pro 1809
• Python version: 3.7.4
• Type of virtual environment used: N/A
• Relevant/affected Python packages and their versions: XXX
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): XXX

Expected behaviour

The correct work of the parser, error detection, suggestions for quick input.

Actual behaviour

After a couple of minutes of writing the code, the Python parser hangs on one of the errors, after it it no longer detects new errors, offers no options for quick input, and so on. It seems that the module is simply turned off. The problem persists until VSC restarts.

Steps to reproduce:

idk

1. Create a folder and open
2. Create py file
3. Write about 1-20 minutes of code and try to make a couple of errors so that the parser will notice them
   My problem occurs 100% of the time and is completely independent of anything, it appears most quickly when the parser sees an error or immediately upon opening the file and trying to load the libraries, but sometimes the problem may arise out of the blue while I move away from the PC.

Guys, if you know some workaround for this problem, even to understate the module version (if this is possible), please write to me, it’s very uncomfortable to write code with this problem.
