Can confirm this. Happens all the time for 4.25 and 4.26 on one of my workstations
It doesn’t happen on another workstation, tho.
The workstation where it fails has a Ryzen 2700x and a RTX 2070. All drivers up to date and it really crashes after like 2 minutes of working. usually when I add a variable, drag some BP-thingy around… it’s just really annoying.
