Found the way to uninstall, I just looked at the wrong spot.
Titanfall is fully reinstalled, however the error still appears.
I'm going to contact the store to see if they can help me.
I'll keep you up to date.

Hello guys
It's been a while since I updated this topic.
I started to get more problems of the same kind, in Titanfall and other games.
I went to the store to fix it and there they came with a solution.
The problem apparently doesn't lay with the GPU, but with a software problem.
They had to reinstall all the software (including Windows 10).
All my games are now reinstalled and everything runs smoothly.
Thanks for the help guys.
