Short description of error
[Please fill out a short description of the error here]
I get a .py export error and whole bunch of code out put. The export fails

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
Take default cube
go to edit mode
Scale bottom face to zero
select top face and scale slightly
select all
switch to edge mode
then press ctrl+b and bevel all edges slightly
go back to object mode
Set scale and rotation through 'ctrl+a'
then go to export as fbx

Only way i have found to resolve this is buy cleaning up the mesh to remove verts that are to close to one and another

Thx for the repro case!
This was a long-standing issue, see #79775 (Something in Blender can generate invalid (Nan) values in UVMaps)
But seems it is finally fixed in 3.0, will check which commit fixed this.
Please check a 3.0 build from https://builder.blender.org/download/daily/

Hm, just noticed that mesh.validate() fails after the bevel, but the FBX export still works, so needs another look...

So, turns out this was fixed with b21db5e698.
Will put this on the list #88449 (Blender LTS: Maintenance Task 2.93).

Will close though, thx reporting!
