Has anything changed on your system recently? Windows update, additional software?
No, all i did was fallowing this tutorial 
Be wary of what you find on YouTube especially when your problem appears different as Vegas isn't "stopped working" on you.
Try a "Factory reset". Instructions here https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/ Make sure you tick the box to clear the cache.
Didnt work, still havent got it.
Looks like you deleted MagixAVC and MagixHEVC. I'd reinstall VEGAS and never follow such a tutorial again.
Thank you guys. It worked, i reinstalled Vegas.
