Minimal reproduction URL

https://github.com/jochenschmich-aeberle/tsx-dynamic-import-error

Problem & expected behavior (under 200 words)

• What happened: My reproduction example produces the expected output with Node 18, but not with Node 20. This happens since tsx version 4.12.0. The README.MD file contains a test case to confirm this.
• What I expected: That all variant*.ts files would always log 2 - regardless of it's module type in the package.json or NodeJS / tsx version.
• Error stack trace: None
• Documentation links: https://github.com/jochenschmich-aeberle/tsx-dynamic-import-error/blob/main/README.md
• Screenshots: None

Bugs are expected to be fixed by those affected by it

• I'm interested in working on this issue

Compensating engineering work will speed up resolution and support the project

BTW for the minimal reproduction, just the cjs directory suffices.
