Problem loading multiple files Filament

Hello everyone. I am using Filament version 3, and at a certain point, the file upload form stopped working, although I assure you it worked before. Specifically, what happens is that if I don't use the ->multiple() method and therefore upload only one file, everything works perfectly including the preview. However, if I use the multiple method, not only does it not show the preview, but the files are not saved either. In the model, I have inserted the array type, expanded to all file types, checked in the php.ini file that it accepts multiple files and a maximum size of 10 MB, excluded the assignment of names, and ensured that the "attachment" field is of the text type. Honestly, I don't know what else to try. Does anyone have any suggestions since it used to work correctly? Here is the code. Thank you all
