Build fails with "filename, directory name, or volume label syntax is incorrect" error in typenum crate

[OmChillure]

Problem

When attempting to build my Anchor project, I'm encountering consistent errors related to the typenum crate. The build process is unable to read the "op.rs" file, resulting in multiple errors.

Error message:
error: couldn't read \?\F:\scaff\journal\anchor\target\release\build\typenum-b4aec6864503f063\out/op.rs: The filename, directory name, or volume label syntax is incorrect. (os error 123)
--> C:\Users\Om Chillure.cargo\registry\src\index.crates.io-6f17d22bba15001f\typenum-1.17.0\src\lib.rs:72:5
|
72 | include!(concat!(env!("OUT_DIR"), "/op.rs"));
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Steps

1. Create a new Anchor project
2. Add necessary dependencies
3. Run anchor build

Possible Solution(s)

No response

Notes

• This error occurs consistently across multiple builds.
• I've tried cleaning the project and rebuilding, but the issue persists.
• The error seems to be related to file paths, possibly due to Windows path length limitations or permissions issues.

Thanks for the report. This seems to be a duplicate of #13919 and #14449. Close in favour of them
