Bug when exporting an fbx project

Hello I come to contact you today because I have a big problem that I can not solve.
I am doing a project on blender 3.2.0.
I received an error yesterday that told me "that certain uv didn't work" so I tried to search and I found the texture that gave me the error every time I added it.
So I decided to redo my whole project because this texture was part of my whole project and apart from deleting it I couldn't find anything that fixes it.
I just finished and I try to export in fbx, and I still find the same error but which is on another texture or other I don't know anymore if it's really the problem

Here is the error:

System Information
Operating system: Windows 11
Graphics card: 7900xt

Blender Version
Broken: 3.2
Worked: 3.2

Short description of error

One of your meshes has a UV Map with invalid/corrupted UVs. There is an existing issue with some more information here: #102783

If you can provide the steps you used to create this invalid mesh, then Blender developers might be able to track down and fix what is causing the UVs to become invalid/corrupted. If you can determine when your scene goes from being able to be exported as FBX to not being able to be exported as FBX that would be very helpful. If you can provide any of this information, I recommend you send it in the existing #102783 issue.

This is a script I copied from another duplicate of this issue. If you copy and paste the script into Blender's Text Editor and run it, it will fix all mesh objects in your .blend file and print which ones had to be fixed into the System Console:

import bpy
for obj in bpy.data.objects:
    if obj.type == "MESH" and obj.data is not None:
        if obj.data.validate(verbose=True):
            print(f"Error found: object {obj.name} had invalid mesh data!")
