Expected behaviour
I have been using the language server and pylint and everything was fine until recently. However, now from time to time I experience random parsing errors on tokens that are not even in the file.
Actual behaviour
As shown in the figure below, the parser shouts these errors regarding "eman", "tnuococa", which are not in the file. There are other errors also. The actual file can be executed normally by an interpreter.
After inspecting the logs below, my guess is that it has something to do with this sol.py.4f805ae93a314088ee8dc430f8bf5945.py file. The actual file name is sol.py so the other file is probably some temp file generated during the execution of the extension.
from typing import List
class Solution:
def accountsMerge(self, accounts: List[List[str]]) -> List[List[str]]:
# * set and map
account_map = {}
for account in accounts:
name = account[0]Steps to reproduce:
- I can't really find an exact way to reproduce this. Usually when I first open a file the parser works fine. Some time later during editing it breaks. Reloading the window solves the problem temporarily.
Logs
The real project path has been replaced by <project_path> for privacy concerns. It only contains English letters (a-zA-Z) and backslashes.

On second thought the strange file name could also be because of git. And reversing the Python extension version to 2019.6.24221 doesn't solve the problem. So the cause might have something to do with git integration for either vscode or the Python/git extensions because I recently initiated the project as a git repo.
