Unreal Engine 4 crashing for every little things

Crash usaly dumps info info logs, can you paste log after crash here from Saved/Logs of your project directory? Also is it C++ project? do you enabled any plugins?

I’m using UE for a game development class and it keeps crashing from the very beginning I downloaded this.
To give you a few examples, UE 4.20 will crash when I…
Launch a new project,
Create a new material,
Create a mask,
Add texture,
Rename a layer,
Move a layer,
Open blueprint,
Make changes to the blueprint, and
Send a crash report and restart.
I don’t think my computer is the problem because I have intel core i7.
I tried deleting and downloading the software but the issue wouldn’t go away.
I hope someone can help me solve this issue. Thank you.
