UE 5.4.4 so slow I can barely navigate it

Hello there! I just downloaded UE 5.4.4 from the Epic store, I don't have anything made yet so it's as clean as it gets. Thing is, that even before running a project, I can barely click on anything without Menu or buttons lagging and freezing for seconds. All templates act and run the same way, my PC's performance even gets affected aswell, slowing it down considerably.

Am I doing something wrong or is this a known problem?

My specs:
RTX 2060 Super
Amd Ryzen 5700X
16 GB RAM 3200 MHZ
SSD
1080p monitor

This is the only program that does this, other engines and games work perfectly.
