Random PC Crashes 4.21

I am experiencing random crashes when using my map in Ue 4.21 . So this is a very weird thing happening its completely random but mostly when placing or removing Foliage. The entire pc randomly blue screens with no error codes. I thought this was a hardware issue. Replaced; hard drive, New clean version of windows, New ram, New Gpu and update all drivers. But still randomly get these crashes. Checked the blueprints being used and no Errors. I even tried setting the editor to low settings.
What is weird about this is once I publish my game I can play it for hours on medium settings but instant crash on Epic settings. Also I can play almost any game out there fine on the highest settings for hours.
But as soon as I go into the Ue4 editor and open my main map Ue4 becomes extremely unstable even on the lowest settings. I tried using a test map (starter demo map) same thing. I even tried updating to the new nvidia creator drivers.
Nothing is working and I’m not getting any error codes please help.
