Tried some tips from other posts, and reinstalled a few times, but nothing has worked.
%LOCALAPPDATA%/Docker/log.txt keeps printing repeatedly:

Guess it probably happened after the most recent update, wondering if anyone has run into a similar problem?
Likely to be a bug of 4.1.0.0, I have reverted to 4.0.1.0, and it is working now.
