Controller won’t load a file once its a saved file

Once I make a lightburn file, my laser won’t load it. I hit send and it shows the loading of the file sending but the laser won’t accept it, it seems. Now if I open a new file and copy paste the same cut or engraving on the new file before saving it, hit send the laser accepts it just fine. I just updated to the newest LB version hoping that would clear the issue but it didn’t. I currently have to open a saved LB file, copy the layers and then open a new file and paste then hit send before the laser will accept it.
