node index.mjs with import 'tsx' results in TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"

Your minimal repro doesn't use tsx.

Oops sorry, looks like that got removed while I was testing. I have put the import 'tsx' back in but the result is exactly the same.

Ok thanks. I did wonder if this might be the answer but I'm not entirely clear on the reason for it. My understanding was that all of import 'tsx' should execute first (which would include the register call) before we try to import './foo.ts'.

Possibly something to do with parallelisation? Or is it just that node doesn't want to complicate things by allowing hooks to be added within the loading of a file?
