I thank all those who helped me to solve my problem, at the same time I asked for help here, I also sent a request for help to the moderators of the game on the website of TrucksMP.
I solved my problem thanks to all of you and I will be enormously grateful.
Below I leave the link of the publication that solved me definitely the error that my game had.
Thank you so much for everything.
Postscript: I think it's pretty obvious to say that I need help from the Google translator to be able to communicate with all of you.
