2022.2.19f1 - WebGL fails to build when enables exceptions is set to 'NONE'

Unity Engine

Same error as a year ago and a few years ago;

2022.2.19f1 is not ‘officially’ out but available on Unity HUB.

An element with the same key but a different value already exists. Key: 'DISABLE_EXCEPTION_CATCHING'

I can confirm this problem, I ran an automated build with Unity 2022.2.19f1 from game.ci on this repo.
Here is the full exception stack trace:
Exception Stacktrace No exceptions

Internal build system error. BuildProgram exited with code 1.

Also when building a development build or other builds I get this exception:

For 2022.2.18f1 I had no problems with the same setup.

Yes! we are aware of this issue and a fix should have landed in 2022.2.21f1.
