System Information
Operating system: Windows 10 64-bit (Build 19043)
Graphics card: Nvidia RTX 3070
Blender Version
Broken: 3.0.1, 3.1.2
When applying a bevel modifier it sometimes causes zero area faces:
It seems it places two vertices on the same location which then causes the triangle to become a flat line.
This happens with a default cube unwrap without any user defined seams so I'm not sure if it counts as the same bug as this one
These zero area faces cause issues in unreal and makes the non-destructive approach with modifiers impossible since you need to apply the modifier and then unwrap the mesh afterwards to get workable UVs
Exact steps for others to reproduce the error
Create a cube
Add bevel modifier
Apply bevel modifier
Look at the UVs, they should now appear as pictured above, broken

Thanks for the report. I can confirm this. Same issue I found in previous versions (2.83)
@howardt , is this a known limitation? Is this the same issue as reported in #56625?
This is the same bug as in #56625 , which I am working on fixing now.
Thank you. I'll merge this report.
