🙁 Actual behavior
I have a project using graphql. Together with him I use a package for code generation. A large file with types is generated. Based on one of the types, I want to make a form in react-hook-form. It works great until you need to extend this type.
If you comment out the 12th line in the src/test file, then tsc will work, otherwise it freeze
when logs are turned on, the problem disappears
🙂 Expected behavior
tsc not freezes :)

Research direction
Start with the linked CodeSandbox and reproduce the freeze in src/test.tsx, comparing behavior with line 12 commented out. Investigate why enabling logs changes the result; done means tsc completes without freezing for the supplied example.
