    V8 asserts the evaluation of the module's async function to succeed without exception. However, the problem is that TerminateExecution initiated by process.exit is breaking that assumption. I'll work on this and submit a fix to v8.

    @sajal50 yeah, it is still under review at https://chromium-review.googlesource.com/c/v8/v8/+/3696493.

    https://chromium-review.googlesource.com/c/v8/v8/+/3696493 has landed. I'll continue to investigate if node handles these termination exceptions properly.

    @legendecas I've tried to cherry-pick your commit in node repo, but it looks like it relies on V8 APIs that are not available in the version of V8 we are using. Do you know if it's worth a backport or if we'd be better off waiting for V8 10.5 to stabilize?

    @aduh95 thanks for the ping. I think the patch should be straightforward to be backported. Submitted #43751 and added a test case for the issue.

    Another reproduction case (it's weird, remove join and it works?):

    import { join } from 'node:path';
import { isMainThread, Worker } from 'node:worker_threads';

if (isMainThread) {
    new Worker(new URL(import.meta.url));
    await 0;
} else {
    process.exit();
    join();
}

    Is there a chance for this to be backported into Node.js 14?

    @szmarczak I tried a backport but V8 has changed a lot since v14. It might need a totally new patch for the issue on v14 (and a refresh review on the patch too).
