Uninstalled the Nvidia driver with ddu in safe mode, uninstalled the Asus GPU Tweak II few times.
same result.
Uninstalled the GPU Tweak II for the 4th time and uninstalled the Nvidia driver again with DDU without safe mode.
worked somehow...
I am 100% sure it will happen again.
And i hope there is a better solution than reinstalling all this stuff all over again and again because it is getting stuck for no particular reason..
(god bless m.2 nvme.. i'd lost it even more if it was on a 2min boot each reinstall instead of a few seconds..)
