UE 4 Constant freezes

Im having a lot of trouble working with UE4, after starting every time after 10 - 20 minutes UE freezes completely, although widows doesn’t freeze, it becomes extremely slow but im still able to kill ue4 with the task manager, im almost sure it triggers while editing a blueprint event graph, i’ve tried v 4.18 , 4.20 and 4.22, and the issue persists, i’ve discarded hardware limitations since i’ve been using the same UE4 installation in the very same machine for 2 years without any trouble, i’ve created several new projects in order to test it (both blueprint and c++ based) every one crashed only with a single blueprint created, only relevant system change i can recall recently was an Avast installation - uninstall and some minor tweaks in the Nvidia control panel (which where applied to a game not UE4).
