System Information
Operating system: macOS Big Sur 11.5.1
Graphics card: Intel Iris Plus

Blender Version
Broken: 2.93.1
(example: 2.79b release)
(example: 2.80, edbf15d3c044, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional)

Whenever I tried to export the model as a .fbx, it would give me an error at unknown location 1.

Error Message:

Thanks for the report. Similar issue has been reported already: blender/blender#79775 (Something in Blender can generate invalid (Nan) values in UVMaps)

Will close this as duplicate
