Error on updating Edge canary: Failed to cache the downloaded installer. Error: 0x800b0001.

Something funny actually happened! I installed Edge canary but with the welcome screen and icons of Edge stable and also without update core!

so what I did was to find the logs in here:

%LOCALAPPDATA%\Temp\MicrosoftEdgeUpdate.log

Special thanks to Deleted for helping me find their locations

then find the URL which was this: (yup it's that long)

http://msedge.f.tlu.dl.delivery.mp.microsoft.com/filestreamingservice/files/edeccdca-d35a-456d-8f21-194f50233db8?P1=1585938496&P2=402&P3=2&P4=o0IWda8WcLn%2bxb8M2B3SzXGW%2fwBO6%2bBBca%2btYj98onxpGswf54avw0enLXaIR0QjBjlH0NQ79mh9UPphVJAx6Q%3d%3d

downloaded it manually, the file name was this:

edeccdca-d35a-456d-8f21-194f50233db8

no extension whatsoever. so I decided to add ".exe" to the end of it because otherwise what can i do with a file without an extension. after that doubled clicking on it silent installed Edge canary.

but it says official build and has no "canary" word anywhere on it

that temporary fixed it, tomorrow or next time when there is a new canary update on the server I will try the online installer and if it fails again I have to keep doing this.

I'm still looking for the reason why this problem apparently only happened to me and an official way to take care of it.
