[benjamint08]

What version of Bun is running?

What platform is your computer?

What steps can reproduce the bug?

Running build.ts in my repo probun - this works fine on Linux. The error occurs when it calls:

It will build my TS into JS in the lib/ folder.

Are you able to reproduce this crash with latest bun (v1.1.20). I believe this issue is fixed
