Error when trying to save a file as a .u3d

[YumeSK]

Hello!

I am trying to save a .obj file as a .u3d, to make it to a 3D PDF later.

But when I try that in MeshLab it says Unkown error (-2147483643)

I am using a Mac ver. 12.3.1 and MeshLab 2022.02
If you need any more info please tell me :D

Does anyone have an idea of how to to fix this error?

Thanks in Advance! ^^
