Unable to load file .framework.js! since updating to Unity 2021.2

Hi,
We've been building a WebGL project fine in Unity 2021.1 I did try out the 2021.2 when it was in Beta to test the improvements they offered, but never could get a build working, it was always missing the framework.js file once built.
Now that 2021.2 is out, we've upgraded our project, and now doing a WebGL 2 build, again I get the same issue, there doesn't seem to be a framework.js file in the Build folder.

Is this a bug? Or am I missing a build setting somewhere?

Any help from anyone would be much appreciated.

 

Tried on 2021.2.2f1 also, still get the same issue.

 

Hey there, I experienced the same thing with our builds, using our own custom build script.
If I made a default "non-development" build with unity's defaults, it would include the framework.js file, if I used my own script that I have been using for years, it would hang (windows 10) trying to do the build. I still have not isolated which setting is causing the issue with my script.
While working with Unity to isolate an unrelated issue -

I came across this issue. I updated to 2021.2.1f1 to try and resolve my other issue and got this, as well as with 2021.2.2f1.
Even though I did manage to make it build using the defaults, the resulting build doesn't load.
I have a bug filed for this -

It happens even with a empty project and a fresh default build with Unity 2021.2.1f1 and 2021.2.2f1
