Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT
What happened: I use :e quite a lot in my vim workflow. As of about a week ago (as I understand it, v0.11.0 was just released), I receive the following error:

What did you expect to happen:
Typically, if the file exists, it is opened. If it is not, VSCodeVim asks if I would like to create the file (I should note this deviates from Vim's behavior, which is to open a buffer with the filename, but that is outside the scope of this bug)
How to reproduce it (as minimally and precisely as possible): Open any file, then press :e any-file-name. The error is then displayed. It's obviously placing the drive root in the path twice, which will cause an error.
Environment:
Typically, if the file exists, it is opened. If it is not, VSCodeVim asks if I would like to create the file (I should note this deviates from Vim's behavior, which is to open a buffer with the filename, but that is outside the scope of this bug)
That issue (https://github.com/VSCodeVim/Vim/issues/2274) was fixed with https://github.com/VSCodeVim/Vim/pull/2392. However, there was a regression reported with https://github.com/VSCodeVim/Vim/issues/2408 and later fixed with https://github.com/VSCodeVim/Vim/pull/2409 about overwriting the file.
The bug you reported is a Windows pathing issue. Fix incoming...
