Nonce invalide

Hello,
I share here a conflict observed between ACF and ACF front end. I implemented an ACF file loading field in Back and Front with ACF front end. When the ACF front end plugin is activated, loading a file from the post editing interface causes an “Invalid Nonce” error. When I disable the front end ACF plugin, the error disappears and the file loads fine.
Can you solve this?
Cordially,
AG
