Bug, SEVERE

Unity says that there is a unknown error with an unknown fix, crashes unity and tells me to report a bug. I am pretty sure, the bug happens more than once and all of the times it happened, it happened while I was trying to import a package from the asset store and it said it couldn't decompress the file. Why I am doing this here instead of just reporting a bug like it asked because when I tried to simply report the bug, when I tried to send it I got this error "error occurred while creating an archive. Error code: Compression failed Failing filename: Assembly-CSharp-editor=firstpass.csproj" and it wouldn't even let me report the bug.
