System Information
Operating system: Windows 11
Graphics card: 3090 RTX

Blender Version
Broken:
3.4.0 alpha
3.2.2 stable

Short description of error

Any exported mesh with custom normals and "triangulate faces" active will result on a mesh with wrong normals.

Exact steps for others to reproduce the error

Starting cube -> add a bevel mod with default settings and activate "harden normals" and "autosmooth" -> export in FBX format with "triangulate faces" setting on and "apply modifiers" -> Import the result. You can check that nice, good looking normals died elsewhere..

Greets and thank you so much for your work.

This is maybe a closely related behaviour, so I'm linking to a BSE Q&A, rather than posting a new bug report:
