Webgl failed to build my project

Hello i’m using 2018.3.2f1 personal
i used to build prototype of my project (unity 2D) with unity 2017 without any problem
Now i can build an empty project but not mine anymore… maybe there are scripts or something making an error…
I try to build in asset folder (unity don’t want), in a folder at the root of the project (D:\Unity\UsineWeb\ ) and another time outside the folder c:\my project. all tests with only 1 result : folder empty and this message
Unity console :

FileNotFoundException: D:\Unity\UsineWeb\Temp\StagingArea\Data\linkresult_wasm\build.wasm does not exist

there isn’t a unity’s member to enlight me and help me make webgl run again with 2018 unity ?! :frowning:

I make a test by using the assets from unity 2018 version with webgl not working and import all in a new 2017 instance: all prefab are missing, all stages are in a mess BUT i can create a webgl build and play it ! So… I ether start from scratch a unity 2017 version of my game… or waiting for a kindly answer from unity’s members to move forward !

As i said, i can build with webgl an empty new project with 2018 version… so it seams it’s a problem with one or more scripts i’m using !
I uploaded the log in my first post.

Thanks by advance for your help

there isn’t any unity’s members or forum members knowing this problem with a solution?

I have the same problem 1: 1. Please write, how did you overcome it?

Try going through the Editor log window in detail, I think there should be an earlier build error hidden in one of the error messages, which causes the build to fail, and then result in another error about the build.wasm not being present?

Done!
Simply, reinstall Win10.
