+`crypto` module. In such cases, attempting to `import` from `http2` or
+calling `require('http2')` will result in an error being thrown.

+When using the lexical ESM `import` keyword, the error can only be
+caught if a handler for `process.on('uncaughtException')` is registered
+_before_ any attempt to load the module is made (using, for instance,
+a preload module).
+
+When using ESM, if there is a chance that the code may be run on a build
+of Node.js where crypto support is not enabled, consider using the
+`import()` function instead of the lexical `import` keyword:
