Internal Error: The compiler crashed when compiling this element.

The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.

Please include the following information:

• the name and version of your operating system,

• the Dart SDK build number (3.6.2), and

• the entire message you see here (including the full stack trace
  below as well as the source location above).

Summary: Dart2js compiler crashed with exit code 253 due to an unexpected kernel SDK version mismatch. The error points to a problem in the compiler, not the user's code.

Are you able to reproduce this issue reliably?

This error points to some mismatch of the versions for assets used to perform the compile so it seems like perhaps there was a stale build cache?
