Ok… after a bit of lurking and tears I found the answer.
Gonna leave it here for anyone in the future. turs out that, when nvidia drivers perform an update or change in engine, it does not mean that it resets the installation to some sort of ‘default’.
So, what correct it for me, was going into the nvidia driver and selectin ‘Manual’ installation. In there, you gotta select the ‘Perform a clean installation’ so it gets rid of the nvwgf2umx error.
Legit do not unerstand how is it that a changing driver does not perfom a clean installation, but there u go.
Hope no1 ever encounter this problem, but also hope this helps
