Vrtk controller objects are destroyed on run.

Hello i experienced something really strange i am driving myself crazy trying to fix it. Suddenly from what seem to be nowhere the ability to access the vive controllers was lost, they dissiperar on runtime, not just the mesh but the whole GameObject. I tried searching online and even uninstalled unity to latest version, well vrtk don’t work on the latest. So now i am back to unity 5.6.2, and the problem is still there. It is not just my apps, if i open vrtk example scenes the same problem persist, i have no idea what to do.
Is there anyone who experienced this and have a solution, it does not work creating a project from scratch, vrtk don’t work.
If i download the latest version of unity i get some error saying that the texture class is protected and cant be accessed.
Also do anyone know what version of unity is best for vrtk, i don’t like these kind of bugs that totally ruined by whole day.
If this is the wrong place to post this, please direct me to where this question is better suited.
Thank you for all your help, and have a nice day.

A little update on things i have tried.
I reinstalled steamvr, still nothing changed. Finally i tried doing without vrtk and using openvr directly, and it works i can interact with my controllers.
This is not a solution, but a confirmation that there is something that made vrtk not working, i really want to continue using vrtk, so i would love all the help i can get, getting it to work again.
I just don’t understand why it worked yesterday and not today, i mean even going from a fresh install and doing projects from scratch in vrtk don’t work.

Latest SteamVR SDK from asset store no longer supports/works with Unity 5.x

VRTK from github supports latest Unity 2018.1 release

Thank you. i guess it is the only proper way by taking the latest version from github. Well good thing i am relatively early stages in my development, so i lost a day or two not an month.
Then i will be sure to get the latest unity at the same time, no sense in working on old versions when i can with new.
