Edit in - Photoshop Beta from Lightroom classic doesn't open the TIFF in Beta

I use to open an image in Beta or Photoshop directly from Lightroom with the menu "Edit in (or modify in) -- Adobe Photoshop or Photoshop Beta".

Since I updated Beta today, thsi fonction doesnt work anymore. Beta opens but the image is not. It stays on the homepage of Beta. Same with Photoshop. 

And if I do "Edit as a dynamic object in Photoshop", it opens and I can modify my image but when I save to go back on Lightroom, ther is this error message:  

Erreur 21: undefined n'est pas un objet.

which means "Undefined isnt an object"

Any idea? Thanks which means Unedfined isnt an object
