Sharing violation on WebGL Build with GZip
Hello,
I have a problem building my game when GZip compression is enabled. Note that when I build the game for WebGL with compression disabled, it builds and runs fine.
When GZip compression is enabled, the build progresses as far as "compressing build result", then it stops with the following error:
IOException: Sharing violation on path C:\Users\Dev\Game\Temp\StagingArea\Data\Output\Build\Game.asm.code.unityweb.compressed

There are some answers how to solve this error when it occurs on running the game, but I couldn't find anything about building the game. As far as I can tell, no other process is running in the build directory. I also tried different build paths, the error stayed the same. Any help is appreciated!
Additional infos: Unity version: 2017.3.1f1 64bit OS: Windows 10
Found the answer myself when opening another project for comparison: The first build after opening a project works just fine, the second build always fails with the above exception on my machine. Closing the project (by closing unity or opening another project) and reopening it fixes this. It seems to be a bug (in Unity 2018.1.1f1 as well), so I filed a bug report.
Summary: Restart Unity before building when you encounter this error, might be a bug.
