Update from 188.8.131.52 to 184.108.40.206 will cause the source analysis failed to work.
I use the package generated from here to update wingide from 220.127.116.11 to 18.104.22.168. But after the upating, I find that the source analysis failed to work and all of the previously resolved completions for the same project were disabled.
I tried to remove all of the caches and change the python interpreter to others and then change it back. But all of my tries are in vain for solving this problem. Finally I revert the update to the original installed version and the problem disappear immediately.
I don't know whether this is a bug of this update.
