Layer export to local database causes geometry changes

[xiaosagua]

What is the bug or the crash?

Create temporary layers in QGIS with a geometric type of face. When exporting to the local GDB database, the geometry of the face changed, but the area did not change (not due to overall displacement or expansion of the graph), resulting in errors in calculating the area. I have also tested the spherical and planar coordinates, and have encountered similar problems. May I ask what is the reason for this?

Steps to reproduce the issue

Versions

3.34.9

Supported QGIS version
