Confirmed, having a closer look now...
You have a couple of UVs with undefined positions (NANs) in "UVMap" ("UV1" doesnt have these and exports fine)
Can be checked with this script:
should give you following output:
Question is where these come from in the first place, because these can cause problems with all kinds of tools.
Was this unwrapped in blender? Or imported with one of the official addons?
(I wasnt able to produce NAN UVs with blenders unwrapping methods, so if you use these, you should be fine and able to export)
Like I said, I dont think it is even desirable to let the FBX exporter check for these NAN (would make it slower) and time is better spent investigating where these NANs come from (to also prevent other tools having trouble with them)
note: I havent spent time investigating if there is a quick method to do a cleanup on these UVs (get rid of the NANs)
Marking as incomplete until we get an answer on how these UVs were generated...
