I don’t see the problem. Yes, it’s not the prettiest or most cleanly finished carbon, but it looks intact.
The odd shaping of the hole is by design. The derailleur hanger most likely has the threads for the through axle, and keys into that shaped hole.

Nobody here is gonna give you a good answer. This is more an engineering question not a mechanic question. The hole is too symmetrical for it to be wear. It looks like it was designed like that intentionally.
Contact the frame manufacturer. Even the most experienced bike mechanic has max 10 years of experience with that kind of cf frame since directional layups haven’t been around long, neither have thru axels.
