[Bug] FileNotFoundError: [WinError 3] The system cannot find the path specified

[Kristinita]

1. Summary

I don't understand, how I can exclude folder, which I already delete.

2. Expected behavior

Successful run AddFolderToProject commands. No stack trace in console.

3. Actual behavior

Traceback (most recent call last):
  File "D:\Sublime Text 3 x64\sublime_plugin.py", line 720, in is_visible_
    ret = self.is_visible()
  File "AddFolderToProject in D:\Sublime Text 3 x64\Data\Installed Packages\Add Folder To Project.sublime-package", line 76, in is_visible
  File "AddFolderToProject in D:\Sublime Text 3 x64\Data\Installed Packages\Add Folder To Project.sublime-package", line 26, in exists

5. Steps to reproduce

I reproduce the problem in a version of Sublime Text without plugins and user settings.

I add D:\Mega.co.nz\MEGAsync Загрузки\Джинджерины\ТТД folder to project → I delete D:\Mega.co.nz\MEGAsync Загрузки\Джинджерины\ТТД folder from my PC.

I restart Sublime Text → I get stack trace.

I open any file → Ctrl+Shift+P → Add Folders To Project → I get stack trace.

6. Environment

Operating system and version:
Windows 10 Enterprise LTSB 64-bit EN
Sublime Text:
Build 3126

Thanks.
