Is there a required condition?\r\n\r\nAlways.\r\n\r\n### What is the expected behavior? Why is that the expected behavior?\r\n\r\nThe worker thread should start with the hooks register successfully.\r\n\r\n### What do you see instead?\r\n\r\nThe process hangs.\r\nRemoving the `register` call will solve the problem.\r\n\r\n### Additional information\r\n\r\nThis problem happens due to #52706, as already triaged in #53097.\r\n\r\nAn additional problem is that the suggested workaround forces people to use `node --import register.js` in order to solve the problem as the module thread is shared with Workers. \r\nWhile this is fine, there might be situation in which users cannot use `--import` (or `--require`). \r\nIn those situation I have observed the `register` call will successfully work for subsequent dynamic `import()` call but **NOT** for `require()` (unless I missed something obvious).\r\n\r\nI created https://github.com/ShogunPanda/hooks-repro to reproduce this.","author":{"url":"https://github.com/ShogunPanda","@type":"Person","name":"ShogunPanda"},"datePublished":"2024-05-28T08:29:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":21},"url":"https://github.com/53182/node/issues/53182"}
