Bug

Hello I'm having a bad time with the game after the last update POE2. The game non stop crashes and it's lagging. And I don't know what to do, it's unplayable. The keyboard stopping from time to time as well. Here's what I've done so far : Changed the keyboard adapter from USB 2.0 to USB 3.0 and changed the batteries, instead of Wi-Fi now I'm using wired connection and I've done many speed tests as well and the connection looks fine. Updated my video card drivers and it is still crashing and lagging. Any suggestions will be appreciate.
