Okay, thanks for your help
I just tried with the 26.0.55 version for Mincraft 1.14 and it works now while the 26.0.33 did not work when I created this topic.
On the other hand, for the version Forge 25.0.219 for Minecraft 1.13.2, it is this version that I used and that works now.
In short, everything works now ?
