[Solved] Nextion display doesn't wrk in game

Hi everyone, I finally started my project!

I know Nextion Display are not supported anymore, but I have one old one that should still work.

I followed all the tutorials, and all I could find here on the subject. I could upload the dash on my nextion, I tried with Nextion editor, Simhub uploader, and sd card, all work fine there. The display is recognize in simhub, FPS value are ok. I used simhub template as a start, checked the mapping, here also evertyhing is ok.

But when I start the game, nothing is shown on the display... It stays with its default values...

has anyone already got this issue and way to fix it?

Thank you all!
