ASUS TUF A15 hinge broken, screen keeps falling down

I have an ASUS TUF Gaming A15 (2023) FA507NV.

The screen hinge area plastic is broken, and the hinge is pulling out of the plastic frame, so the screen won’t stay open and keeps falling forward.

I already:

• Opened the laptop
• Disconnected the battery
• Removed the hinge area

The metal hinge itself seems fine, but the plastic housing/mount is cracked and broken.

My questions:

1. Do I need to replace the entire back cover / screen housing, or is there another fix?
2. Is this a common issue with this model?
3. Where can I buy the correct replacement part?

I added photos for reference.

Thanks.
